Abstract:

Fast-growing countries tend to experience rapid export growth with little secular change in their terms of trade. This contradicts most international macroeconomic models, which predict that productivity and labor supply shocks can affect exports only through changes in the terms of trade. This paper generalizes the monopolistic competition trade model of Helpman and Krugman (1985), providing a basis for growth-led exports without declining terms of trade. The key mechanism behind this result is that fast-growing countries are able to develop new varieties of products that can be exported without pushing down the prices of existing products. There is strong support for the new model in long-run export growth of many countries in the post-war era. These results have major implications for the analysis of supply shocks in international macroeconomic models.

Abstract:

We introduce a new high-frequency foreign exchange dataset from EBS (Electronic Broking Service) that includes trading volume in the global interdealer spot market, data not previously available to researchers. The data also gives live transactable quotes, rather than the indicative quotes that have been used in most previous high frequency foreign exchange analysis. We describe intraday volume and volatility patterns in euro-dollar and dollar-yen trading. We study the effects of scheduled U.S. macroeconomic data releases, first confirming the finding of recent literature that the conditional mean of the exchange rate responds very quickly to the unexpected component of data releases. We next study the effects of data releases on trading volumes. News releases cause volume to rise, and to remain elevated for a longer period. However, in contrast to the result for the level of the exchange rate, even if the data release is entirely in line with expectations, we find that there is still typically a large pickup in trading volume.

Abstract:

Empirical estimates of the benefit of financial intermediation are constructed by examining the role played by local banks in facilitating syndicated loans to borrowers in emerging market countries. Assuming that local banks possess a superior monitoring ability, the market is ideal for studying the value of intermediation since cross-border lending into emerging markets is plagued by particularly high information and agency costs and the supply of local bank capital is in limited short run supply. Using variation in the propensity of local banks to participate in foreign arranged syndicates, there are two economically important results. First, local banks are much more likely to participate in unconditionally riskier loans. Second, after controlling for borrower characteristics, loan characteristics, and the endogeneity of the local bank lending decision, loans with local bank participation have spreads that are 10 percent lower (29 basis points) than otherwise similar loans. Combined, the results support the conclusion that local banks, a particularly special type of financial intermediary, provide value by considerably reducing financing costs, especially for riskier borrowers.

Abstract:

Using data from the IMF Coordinated Portfolio Investment Surveys conducted in 2001, we analyze the determinants of 31 countries' international equity holdings. We show that investors in all countries underweight U.S. equities in their portfolios, many by more than they underweight foreign equities in general. Such behavior is surprising given the common perception of the United States as a desirable investment destination due to its well-developed legal and regulatory environment. Instead we find that investors in some countries are overweight in equities from other countries with which they have close regional or political ties. Such ties, along with distance, trade, issuance of U.S. ADRs or cross-listing on the London Stock exchange, market concentration, and estimated betas, help explain patterns of diversification. However, even when all these variables are included, we find significant fixed effects for most countries, suggesting that a considerable amount of cross-country variation in investment positions and in home bias remains to be explained. Our work confirms previous findings and extends results most completely documented for the United States to other major investor countries. But it also suggests caution should be used when interpreting results derived from studies of one or a few countries.

Abstract:

This paper examines the relative importance of global, country-specific, and industry-specific factors in both the cash flow and discount rate components of equity returns between 1995 and 2003. Our framework draws upon previously separate literatures on country versus industry effects and (forward-looking) cash flow versus discount rate components of equity return innovations. We apply the Campbell (1991) decomposition for industry-by-country, all-country, global industry, and world market index returns so we can produce a richer characterization of same-industry and same-country effects in stock returns. Unlike previous equity return decomposition papers, we exploit information in equity analysts' earnings forecasts when projecting future variables from our reduced-form equation systems. Our findings confirm previous research that finds patterns of correlation that suggest a richer underlying structure than just a single common global factor. Furthermore, our results suggest that global, within-country, and same-industry effects are all important for both of the two key components of stock returns: news about future dividends and news about future discount rates. In particular, within-industry covariation in news about future discount rates appears to be just as important as within-country covariation in news about future discount rates. We also find that the idiosyncratic component of cash flow news is more important than the global component, while the reverse is true for news about future discount rates. Our results are broadly consistent with co-movement in future discount rates arising from perceptions of common elements of risk, rather than national market segmentation.

Abstract:

This paper evaluates the performance of U.S. investors' portfolios in the equities of over 40 countries over a 25-year period. We find that these portfolios achieved a significantly higher Sharpe ratio than foreign benchmarks, especially since 1990. We uncover three potential reasons for this success. First, U.S. investors abstained from momentum trading and instead sold past winners. Second, conditional performance tests provide no evidence that the superior (unconditional) performance owed to private information, suggesting that the successful exploitation of publicly available information played a role. Third, the documented preference for cross-listed and well-governed foreign firms appears to have served U.S. investors well. We conclude with a short discussion of the implications of our findings for the home bias literature.

Abstract:

This paper uses a sample of 4,410 firms from 29 countries to investigate the relation between corporate governance and the shareholder base. In contrast to previous work, our results strongly support the notion that poor corporate governance, at both the firm and country level, negatively impacts the willingness of foreign investors to hold a firm's equity. Specifically, we find that firms whose managers have sufficiently high control rights that they may reasonably be expected to expropriate minority equity investors attract significantly less U.S. investment, especially in countries with poor external governance. Our findings suggest that the prices U.S. investors are asked to pay for firms with poor governance are not low enough to fully compensate them for expected expropriation or increased estimation risk associated with expected poor disclosure by these firms. Because prior research shows that a smaller shareholder base is associated with a lower firm value, our results are consistent with the notion that the shareholder base represents an important channel through which poor expected corporate governance contributes to a reduction in firm value.

Abstract:

We use a comprehensive 1997 survey to examine U.S. investors' preferences for foreign equities. We document a variety of firm characteristics that can influence U.S. investment, but the most important determinant is whether the stock is cross-listed on a U.S. exchange. Our selection bias-corrected estimates imply that firms that cross-list can increase their U.S. holdings by 8 to 11 percent of their market capitalization, roughly doubling the amount held without cross-listing. All else equal, we find that firms experience smaller increases in U.S. shareholdings upon cross-listing if they are Canadian, from English-speaking countries, are members of the MSCI World index, or had higher quality accounting standards prior to cross-listing. We argue that these findings suggest that improvements in information production explain U.S. investors' attraction to foreign stocks that cross-list in the United States.

Abstract:

Governments in emerging economies have pursued real exchange rate targeting through Purchasing Power Parity (PPP) rules that link the nominal depreciation rate to either the deviation of the real exchange rate from its long run level or to the difference between the domestic and the foreign CPI-inflation rates. In this paper we disentangle the conditions under which these rules may lead to endogenous fluctuations due to self-fulfilling expectations in a small open economy that faces nominal rigidities. We find that besides the specification of the rule, structural parameters such as the share of traded goods (that measures the degree of openness of the economy) and the degrees of imperfect competition and price stickiness in the non-traded sector play a crucial role in the determinacy of equilibrium. To evaluate the relevance of the real (in)determinacy results we pursue a learnability (E-stability) analysis for the aforementioned PPP rules. We show that for rules that guarantee a unique equilibrium, the fundamental solution that represents this equilibrium is learnable in the E-stability sense. Similarly we show that for PPP rules that open the possibility of sunspot equilibria, a common factor representation that describes these equilibria is also E-stable. In this sense sunspot equilibria and therefore aggregate instability are more likely to occur due to PPP rules than previously recognized.

Abstract:

We offer evidence that interest rate spreads on syndicated loans to corporate borrowers are economically significantly smaller in Europe than in the U.S., other things equal. Differences in borrower, loan and lender characteristics associated with equilibrium mechanisms suggested in the literature do not appear to explain the phenomenon. Borrowers overwhelmingly issue in their natural home market and bank portfolios display significant home "bias." This may explain why pricing discrepancies are not competed away, but the fundamental causes of the discrepancies remain a puzzle. Thus, important determinants of loan origination market outcomes remain to be identified, home "bias" appears to be material for pricing, and corporate financing costs differ in Europe and the U.S.

Abstract:

Changes in monetary policy are typically implemented gradually, an empirical observation known as interest-rate smoothing. We propose the explanation that time-non-separable preferences may render interest-rate smoothing optimal. We find that when consumers have "catching-up-with-the-Joneses" preferences, optimal monetary policy reacts gradually to shocks to prevent inefficiently fast adjustments in consumption. We also extend our basic model to investigate the effects of capital formation and nominal rigidities on the dynamics of optimal monetary policy. Optimal policy responses continue to be gradual in the presence of capital and sticky prices, with a size and speed that are in line with empirical findings for the U.S. economy. Our results emphasize that gradualism in monetary policy may be needed simply to guide the economy on an optimally smooth path.

Abstract:

I present empirical evidence of how the U.S. economy, including per-capita hours worked, responds to a technology shock. In particular, I present results based on permanent changes to a constructed direct measure of technological change for U.S. manufacturing industries. Based on empirical evidence, some claim that hours worked declines and never recovers in response to a positive technology shock. This paper's empirical evidence suggests that emphasizing the drop in hours worked is misdirected. Because the sharp drop in hours is not present here, the emphasis rather should be on the small (perhaps negative) initial response followed by a subsequent large positive response. Investment, consumption, and output have similar dynamic responses. In response to a positive technology shock, a standard flexible price model would have an immediate increase in hours worked. Therefore, such a model is inconsistent with the empirical dynamic responses. I show, however, that a flexible price model with habit persistence in consumption and certain kinds of capital adjustment costs can better match the empirical responses. Some recent papers have critiqued the use of long run VARs to identify the dynamic responses to a technology shock. In particular they report that, when long run VARs are applied to data simulated from particular economic models, the point estimates of the impulse responses may be imprecisely estimated. However, based on additional simulation evidence, I find that, although the impact response may be imprecisely estimated, a finding of a delayed response is much more likely when the true model response also has a delayed response.

Abstract:

We assess the impact of credit ratings on the pricing of structured financial products, using a sample of more than 1300 changes in Moody's or Standard and Poor's (S&P) ratings of U.S. asset-backed securities (ABS). We find that rating downgrades tend to be accompanied by negative returns and widening spreads, with the average effects stronger than those that have been reported in prior research on corporate and sovereign bond ratings. A portion of the negative implications of ABS downgrades are anticipated by price movements ahead of the rating action, although to a lesser degree than has been found for bond ratings. Accordingly, ABS market participants appear to rely somewhat more on rating agencies as a source of negative news about credit risk. Nevertheless, because ABS rating downgrades are relatively rare events, their effects account for only a small fraction of the variance of returns. In contrast to our results on downgrades, market reactions to ABS rating upgrades are virtually zero, on average. Together, the results imply even greater asymmetry in the value-relevance of ABS rating changes than has been found in event studies of changes in bond ratings.

Abstract:

Forward and futures rates are frequently used as measures of market expectations. In this paper we apply standard forecast efficiency tests, and some newer exact sign and rank tests, to a wide range of forward and futures rates, and in this way test whether these are in fact rational expectations of future actual prices. The forward and futures rates that we study under a common methodology include foreign exchange forward rates, U.S. and foreign interest rate futures and forward rates, oil futures and natural gas futures. For most, but not all, of these instruments, we find that we can reject the hypothesis that the forward or futures rates are rational expectations of actual future prices. It is well known that foreign exchange forward rates give less accurate forecasts than a random walk, but we show that this is also true for some interest rate futures and forward rates. We conclude that forward and futures prices are not generally pure measures of market expectations: they are also heavily affected by the market price of risk.

Abstract:

We describe the inflation targeting framework (ITF) and compare it against hypothetical best-practice based on optimization. The core requirements of the ITF are an explicit long-run inflation goal and a commitment to transparency in policymaking. Advocates and practitioners of the ITF have made many contributions to clear goal setting and communication by central banks. However, we contend that ITF communication policies both as advocated and practiced often have some elements that either obfuscate or, in some cases, explicitly contradict the dictates of optimization in a stabilization-policy paradigm. In this paradigm, the central bank has an objective function that places weight on both inflation and output-gap stabilization and faces a conventional (exploitable) Phillips-curve trade-off. We point out some problems that the ITF communication policy may generate in this setting. Our analysis leads us to make four suggestions for communication policy intended to help central banks avoid these problems.

Abstract:

We propose an integrated treatment of the problems of optimal monetary and fiscal policy, for an economy in which prices are sticky (so that the supply-side effects of tax changes are more complex than in standard fiscal analyses) and the only available sources of government revenue are distorting taxes (so that the fiscal consequences of monetary policy must be considered alongside the usual stabilization objectives). Our linear-quadratic approach allows us to nest both conventional analyses of optimal monetary stabilization policy and analyses of optimal tax-smoothing as special cases of our more general framework. We show how a linear-quadratic policy problem can be derived which yields a correct linear approximation to the optimal policy rules from the point of view of the maximization of expected discounted utility in a dynamic stochastic general-equilibrium model. Finally, in addition to characterizing the optimal dynamic responses to shocks under an optimal policy, we derive policy rules through which the monetary and fiscal authorities may implement the optimal equilibrium. These take the form of optimal targeting rules, specifying an appropriate target criterion for each authority.

Abstract:

Recent evidence on the effect of government spending shocks on consumption cannot be easily reconciled with existing optimizing business cycle models. We extend the standard New Keynesian model to allow for the presence of rule-of-thumb (non-Ricardian) consumers. We show how the interaction of the latter with sticky prices and deficit financing can account for the existing evidence on the effects of government spending.

Abstract:

We develop an estimated model of the U.S. economy in which agents form expectations by continually updating their beliefs regarding the behavior of the economy and monetary policy. We explore the effects of policymakers' misperceptions of the natural rate of unemployment during the late 1960s and 1970s on the formation of expectations and macroeconomic outcomes. We find that the combination of monetary policy directed at tight stabilization of unemployment near its perceived natural rate and large real-time errors in estimates of the natural rate uprooted heretofore quiescent inflation expectations and destabilized the economy. Had monetary policy reacted less aggressively to perceived unemployment gaps, inflation expectations would have remained anchored and the stagflation of the 1970s would have been avoided. Indeed, we find that less activist policies would have been more effective at stabilizing *both* inflation and unemployment. We argue that policymakers, learning from the experience of the 1970s, eschewed activist policies in favor of policies that concentrated on the achievement of price stability, contributing to the subsequent improvements in macroeconomic performance of the U.S. economy.

Abstract:

Using a general-equilibrium simulation model featuring nominal rigidities and monopolistic competition in product and labor markets, this paper estimates the macroeconomic benefits and international spillovers of an increase in competition. After calibrating the model to the euro area vs. the rest of the industrial world, the paper draws three conclusions. First, greater competition produces large effects on macroeconomic performance, as measured by standard indicators. In particular, we show that differences in competition can account for over half of the current gap in GDP per capita between the euro area and the US. Second, it may improve macroeconomic management by increasing the responsiveness of wages and prices to market conditions. Third, greater competition can generate positive spillovers to the rest of the world through its impact on the terms of trade.

Abstract:

In a plain-vanilla New Keynesian model with two-period staggered price-setting, discretionary monetary policy leads to multiple equilibria. Complementarity between the pricing decisions of forward-looking firms underlies the multiplicity, which is intrinsically dynamic in nature. At each point in time, the discretionary monetary authority optimally accommodates the level of predetermined prices when setting the money supply because it is concerned solely about real activity. Hence, if other firms set a high price in the current period, an individual firm will optimally choose a high price because it knows that the monetary authority next period will accommodate with a high money supply. Under commitment, the mechanism generating complementarity is absent: the monetary authority commits not to respond to future predetermined prices. Multiple equilibria also arise in other similar contexts where (i) a policymaker cannot commit, and (ii) forward-looking agents determine a state variable to which future policy responds.

Abstract:

How much discretion should the monetary authority have in setting its policy? This question is analyzed in an economy with an agreed-upon social welfare function that depends on the randomly fluctuating state of the economy. The monetary authority has private information about that state. In the model, well-designed rules trade off society's desire to give the monetary authority discretion to react to its private information against society's need to guard against the time inconsistency problem arising from the temptation to stimulate the economy with unexpected inflation. Although this dynamic mechanism design problem seems complex, society can implement the optimal policy simply by legislating an inflation cap that specifies the highest allowable inflation rate. The more severe the time inconsistency problem, the more tightly the cap constrains policy and the smaller is the degree of discretion. As this problem becomes sufficiently severe, the optimal degree of discretion is none.

Abstract:

This paper investigates whether the degree and the nature of economic and monetary policy interdependence between the United States and the euro area have changed with the advent of EMU. Using real-time data, it addresses this issue from the perspective of financial markets by analysing the effects of monetary policy announcements and macroeconomic news on daily interest rates in the United States and the euro area. First, the paper finds that the interdependence of money markets has increased strongly around EMU. Although spillover effects from the United States to the euro area remain stronger than in the opposite direction, we present evidence that US markets have started reacting also to euro area developments since the onset of EMU. Second, beyond these general linkages, the paper finds that certain macroeconomic news about the US economy have a large and significant effect on euro area money markets, and that these effects have become stronger in recent years. Finally, we show that US macroeconomic news have become good leading indicators for economic developments in the euro area. This indicates that the higher money market interdependence between the United States and the euro area is at least partly explained by the increased real integration of the two economies in recent years.

Abstract:

Was the high inflation of the 1970s mostly due to incomplete information about the structure of the economy (an unavoidable mistake as suggested by Orphanides, 2000)? Or, to weak reaction to expected inflation and/or excessive policy activism that led to indeterminacies (a policy mistake, a scenario suggested by Clarida, Gali and Gertler, 2000)? We study this question within the NNS model with policy commitment and imperfect information, requiring that the model have satisfactory overall empirical performance. We find that both explanations do a good job in accounting for the great inflation. Even with the commonly used specification of the interest policy rule, high and persistent inflation can occur following a significant productivity slowdown if policymakers significantly and persistently underestimate "core" inflation.

Abstract:

We analyze welfare maximizing monetary policy in a dynamic two-country model with price stickiness and imperfect competition. In this context, a typical terms of trade externality affects policy interaction between independent monetary authorities. Unlike the existing literature, we remain consistent to a public finance approach by an explicit consideration of all the distortions that are relevant to the Ramsey planner. This strategy entails two main advantages. First, it allows an accurate characterization of optimal policy in an economy that evolves around a steady-state which is not necessarily efficient. Second, it allows to describe a full range of alternative dynamic equilibria when price setters in both countries are completely forward-looking and households' preferences are not restricted. In this context, we study optimal policy both in the long-run and along a dynamic path, and we compare optimal commitment policy under Nash competition and under cooperation. By deriving a second order accurate solution to the policy functions, we also characterize the welfare gains from international policy cooperation.

Abstract:

We examine the performance of forward-looking inflation-forecast-based rules in open economies. In a New Keynesian two-bloc model, a methodology first employed by Batini and Pearlman (2002) is used to obtain analytically the feedback parameters/horizon pairs associated with unique and stable equilibria. Three key findings emerge: First, indeterminacy occurs for any value of the feedback parameter on inflation if the forecast horizon lies too far into the future. Second, the problem of indeterminacy is intrinsically more serious in the open economy. Third, the problem is compounded further in the open economy when central banks respond to expected consumer, rather than producer price inflation.

Abstract:

This paper examines the effects of firing costs in a dynamic general equilibrium model where firms face stochastic demand. It derives analytically two simple closed-form equations, one for the supply of labor, the other for its demand. These equations determine the comparative static effects of changes in firing costs on the labor market. When negative shocks are more likely to occur than positive shocks, and when the frequency of these shocks is high, firing costs have a substantial negative impact on aggregate employment. In addition, product market integration, as it has occurred in the formation of the European Union, induces firms to be more wary of future possible downturns and therefore intensifies the negative consequences of firing costs.

Abstract:

We consider monetary-policy rules with inflation-rate targets and interest-rate or money-growth instruments using a flexible-price, perfect-foresight model. There is always a locally-unique target equilibrium. There may also be below-target equilibria (BTE) with inflation always below target and constant, asymptotically approaching or eventually reaching a below-target value, or oscillating. Liquidity traps are neither necessary nor sufficient for BTE which can arise if monetary policy keeps the interest rate above a lower bound. We construct monetary rules that preclude BTE when fiscal policy does not. Plausible fiscal policies preclude BTE for any monetary policy; those policies exclude surpluses and, possibly, balanced budgets.

Abstract:

We analyze the development of, and foreign participation in, 49 local bond markets. Countries with stable inflation rates and strong creditor rights have more developed local bond markets and rely less on foreign-currency-denominated bonds. Less developed bond markets have returns characterized by high variance and negative skewness, factors eschewed by U.S. investors. Results based on a three-moment CAPM indicate, however, that it is diversifiable idiosyncratic risk that U.S. investors appear to shun. Taken as a whole our results hint at a virtuous cycle of bond market development: Creditor friendly policies and laws can spark local bond market development that enables the development of derivatives markets and, in turn, attracts foreign participation.

Abstract:

We analyze foreigners' and domestic institutional investors' positions in U.S. equities. Controlling for many factors, we uncover a common preference for large firms and firms that are diversified internationally. The domestic preference for internationally diversified firms implies that investors might obtain substantial international diversification by investing at home. Using an international factor model, we show that exposure to foreign equity markets is indeed greater for domestic firms that are more diversified internationally, suggesting that at least some of the home-grown foreign exposure translates into international diversification benefits. After accounting for home-grown foreign exposure, the share of 'foreign' equities in investors' portfolios nearly doubles, reducing (but not eliminating) the observed home bias.

Abstract:

Gali's innovative approach of imposing long-run restrictions on a vector autoregression (VAR) to identify the effects of a technology shock has become widely utilized. In this paper, we investigate its reliability through Monte Carlo simulations using calibrated business cycle models. We find it encouraging that the impulse responses derived from applying the Gali methodology to the artificial data generally have the same sign and qualitative pattern as the true responses. However, we find considerable estimation uncertainty about the quantitative impact of a technology shock on macroeconomic variables, and little precision in estimating the contribution of technology shocks to business cycle fluctuations. More generally, our analysis emphasizes that the conditions under which the methodology performs well appear considerably more restrictive than implied by the key identifying assumption, and depend on model structure, the nature of the underlying shocks, and variable selection in the VAR. This cautions against interpreting responses derived from this approach as model-independent stylized.

Abstract:

In the past few years, observers increasingly have pointed to China as a source of downward pressure on global prices. This paper evaluates the theoretical and empirical evidence bearing on the question of whether China's buoyant export growth has led to significant changes in the inflation performance of its trading partners. This evidence suggests that the impact of Chinese exports on global prices has been, while non-negligible, fairly modest. On a priori grounds, our theoretical analysis suggests that China's economy is still too small relative to the world economy to have much effect on global inflation: a back-of-the-envelope calculation puts that effect at about 1/3 percentage point in recent years. In terms of the empirical evidence, we identify a statistically significant effect of U.S. imports from China on U.S. import prices, but given the size of this effect and the relatively low share of imports in U.S. GDP, the ultimate impact on the U.S. consumer prices has likely been quite small. Moreover, imports from China had little apparent effect on U.S. producer prices. Finally, using a multi-country database of trade transactions, we estimate that since 1993, Chinese exports lowered annual import inflation in a large set of economies by 1/4 percentage point or less on average, similar to the prediction of our theoretical model.
