The Composition of Government Spending and the Real Exchange Rate

We show that the composition of government spending influences the long-run behavior of the real exchange rate. We develop a two-sector small open-economy model in which an increase in government consumption is associated with real appreciation, while an increase in government investment may generate real depreciation. Our empirical work confirms that government consumption and government investment have differential effects on the real exchange rate and the relative price of nontradables.     

High exchange-rate volatility and low pass-through

Two specifications of an open-economy model are shown to generate high exchange-rate volatility and low exchange-rate pass-through (ERPT). In the model, price discrimination causes ERPT to be incomplete in both the short and the long run. In the short run, a small amount of nominal rigidities is enough to reduce ERPT sharply; still, exchange-rate depreciation worsens the terms of trade, consistent with the evidence. Possible biases from omitted variables and measurement error in the ERPT empirical literature (due to data limitations) are investigated using model-generated time series. Estimates of ERPT coefficients can be quite different from true parameters, and are sensitive to the shocks driving the economies. Estimates can nonetheless detect key structural features of the models.     

Is gold a safe haven or a hedge for the US dollar? Implications for risk management

We assess the role of gold as a safe haven or hedge against the US dollar (USD) using copulas to characterize average and extreme market dependence between gold and the USD. For a wide set of currencies, our empirical evidence revealed (1) positive and significant average dependence between gold and USD depreciation, consistent with the fact that gold can act as hedge against USD rate movements, and (2) symmetric tail dependence between gold and USD exchange rates, indicating that gold can act as an effective safe haven against extreme USD rate movements. We evaluate the implications for mixed gold-currency portfolios, finding evidence of diversification benefits and downside risk reduction that confirms the usefulness of gold in currency portfolio risk management.     

Inconsistent Depreciation Practice and Public Policymaking: Local Government Reform in New South Wales

Public policy based on numerical indicators – a form of ‘public management by numbers’ – has become commonplace across the world. Whereas a good deal is known about the deleterious effects of this type of policymaking – including ratcheting, output distortion and ‘gaming’ – unfortunately little attention has focused on the adverse local government policy consequences of inconsistent depreciation accruals by local authorities. This paper seeks to address this gap in the empirical literature on local government performance. After examining the use of accounting data by local government policymakers, the paper reviews available empirical evidence of inconsistent depreciation practice both in Australia and abroad. We then consider the recent New South Wales (NSW) Independent Local Government Review Panel's use of accounting ratios as supporting evidence for boundary change in local government as a case study of the adverse impact of inconsistent depreciation practice. The NSW experience clearly demonstrates the distortionary effects of empirical evidence resulting from significant variation in depreciation accruals by individual local councils. The paper concludes with an assessment of the options available to local government policymakers wishing to obtain more accurate accounting accrual data for policy formulation purposes.     

Expectations of future income and real exchange rate movements

We show that changes in expectations of future income driven by exogenous factors (such as the discovery of oil and an increase in global demand for natural resources) can cause movements in the real exchange rate (RER) in excess of, and sometimes even in the opposite direction to, what one would expect given the changes in current income. We provide both a theoretical model and empirical evidence of this. In particular, we show that the signing of numerous production sharing agreements (PSAs) between the government of Azerbaijan and foreign oil companies in 1994–1998 fueled expectations of higher future incomes, resulting in a considerable appreciation of the RER. Some of these PSAs subsequently failed or ran into difficulties, which led to a downward revision of expected future income and a depreciation of the RER in 1999–2003, even though the current income started to rise, due to an increase in the current oil revenue.     

Foreign currency-denominated borrowing in the absence of operating incentives

It is well known that corporations issue foreign currency-denominated debt to hedge foreign currency cash flows with offsetting interest payments. We test an alternative “opportunistic” motive for foreign currency-denominated borrowing. We do so by constructing a comprehensive sample of foreign currency-denominated bonds issued by sovereign government and agency issuers with no foreign currency cash flows or foreign operations. We find strong and consistent evidence that the borrowers in our sample consider cross-currency differences in covered and uncovered interest yields in choosing the currency in which to denominate their international debt. We estimate the average gains to opportunistic covered yield borrowing to be 4 to 18 basis points. Interestingly, we also find that the average bond offering in our sample precedes a large and beneficial depreciation of the issue currency over the course of the following year. These results support what has been a frequent conjecture in the foreign debt market.     

Explaining Underutilization of Tax Depreciation Deductions: Empirical Evidence from Norway

Many corporations do not claim all of their allowable tax depreciation deductions. Intuitively, this kind of behavior might seem odd. However we propose several possible explanations. First, we find strong evidence that firms facing current tax losses or carrying forward past losses underutilize depreciation in order to recover tax losses before they expire. Second, corporations with bad economic performance tend to underutilize their deductions, suggesting that corporations use costly windowdressing on their accounting measures. Third, we find support for the hypothesis that tax compliance costs discourage the utilization of accelerated depreciation, especially by small firms. We do not find much support for other hypotheses. For example, we find no evidence of substitution between tax depreciation and private debt due to competition between the benefits of private bank monitoring and the tax savings from using tax allowances to postpone tax payments, as suggested in earlier literature. We also study the effects of the uniform reporting accounting system (typical of many European countries) which can, under certain circumstances, constrain dividends. Forgoing some tax depreciation can loosen the dividend constraint, but the evidence does not support this motivation. Unusual access to extremely detailed individual firm tax return forms in Norway made our empirical analysis possible. In addition, the 1992 Norwegian tax reform provided a natural experiment for testing some of the hypotheses. We use the time-series and cross-sectional variation across Norwegian corporations in 1988, 1991, 1992 and 1993.     

How useful is the Marginal Expected Shortfall for the measurement of systemic exposure? A practical assessment

We explore the practical relevance from a supervisor’s perspective of a popular market-based indicator of the exposure of a financial institution to systemic risk, the Marginal Expected Shortfall (MES). The MES of an institution can be defined as its expected equity loss when the market itself is in its left tail. We estimate the dynamic MES recently proposed by Brownlees and Engle (2012) for a panel of 68 large US banks over the last decade and a half. Running panel regressions of the MES on bank characteristics, we first find that the MES can be roughly rationalized in terms of standard balance-sheet indicators of bank financial soundness and systemic importance. We then ask whether the cross section of the MES can help to identify ex ante, i.e. before a crisis unfolds, which institutions are more likely to suffer the most severe losses ex post, i.e. once it has unfolded. Unfortunately, using the 2007–2009 crisis as a natural experiment, we find that some standard balance-sheet ratios are better able than the MES to predict large equity losses conditionally to a true crisis.     

Incentive effects of bonus depreciation

This study examines the effect on capital expenditures of “bonus depreciation,” which was intended to stimulate such spending by allowing businesses to immediately expense a portion of the cost of qualified capital expenditures from late 2001 through 2004. After controlling for many previously documented determinants of capital expenditures, some of our results indicate that capital expenditures during bonus depreciation’s availability were greater than those during the time it was not available, consistent with the expected effect. However, other results indicate that bonus depreciation had an insignificant effect on capital expenditures. These mixed findings generally persist through several sensitivity analyses. We interpret these results as weakly supportive evidence that Congress attained its goal of stimulating capital spending.     

Day of the week effect on foreign exchange market volatility: Evidence from Turkey

This paper assesses the day of the week effect of the daily depreciation of the Turkish lira (TL) against the US dollar (USD) and its volatility. The empirical evidence from Turkey presented here suggests that Thursdays are associated with higher and Mondays with lower depreciation rates compared to those of Wednesdays. Moreover, Mondays and Tuesdays are associated with higher volatility than Wednesdays.     

人民币汇率波动对我国与东亚地区双边贸易影响的实证研究

国际金融危机过程中,东亚部分国家和地区货币竞相贬值以促进出口的做法使得国内要求人民币贬值的呼声甚高。实证结果表明,中国与东亚地区收入水平差距、市场经济化程度以及商品价格水平拉大将导致双边贸易收支的扩大,而人民币相对汇率的升值将缩小中国与东亚地区的双边贸易收支。与此同时．人民币汇率波动对中国与东亚地区贸易收支的影响还存在着国别（地区）效应。对于中国而言,在努力扩大出口的同时应兼顾国家发展战略,坚持产业升级、慎用货币贬值措施,并应通过多次、小幅升值的方式保持人民币的强势地位。     

Chronicle of currency collapses: Re examining the effects on output

The impact of currency collapses (i.e. large nominal depreciations or devaluations) on real output remains unsettled in the empirical macroeconomic literature. This paper provides new empirical evidence on this relationship using a dataset for 108 emerging and developing economies over the period 1960–2006. We provide estimates of how these episodes affect growth and output trend. Our main finding is that currency collapses are associated with a permanent output loss relative to trend, which is estimated to range between 2% and 6% of GDP. However, we show that such losses tend to materialize before the drop in the value of the currency, which suggests that the costs of a currency crash largely stem from the factors leading to it. Taken on its own (i.e. ceteris paribus), we find that currency collapses tend to have a positive effect on output. More generally, we also find that the likelihood of a positive growth rate in the year of the collapse is over two times more likely than a contraction, and that positive growth rates in the years that follow such episodes are the norm. Finally, we show that the persistence of the crash matters, i.e. one-time events induce exchange rate and output dynamics that differ from consecutive episodes.     

Do foreign banks increase competition? Evidence from emerging Asian and Latin American banking markets

In this paper we examine the impact of foreign bank penetration on the competitive structure of domestic banking sectors in host emerging economies. We focus our analysis on Asia and Latin America during the period 1997-2008. Using bank-level panel data to identify foreign banks and to estimate measures of banking competition, we are able to provide robust empirical evidence that an increase in foreign bank penetration enhances competition in these host countries’ banking sectors. We find that this positive foreign bank penetration and banking competition link is associated with a spillover effect from foreign banks to their domestic counterparts. This spillover effect becomes stronger when more efficient and less risky foreign banks enter into less concentrated host country markets. We also find that the spillover effect is greater when foreign banks enter in the form of ‘de novo penetration’ than through mergers or acquisitions of domestic banks (‘M&A penetration’).     

Exchange Rate Changes and Inflation in Post‐Crisis Asian Economies: Vector Autoregression Analysis of the Exchange Rate Pass‐Through

Macro‐economic consequences of large currency depreciations among the crisis‐hit Asian economies varied from one country to another. Inflation did not soar after the Asian currency crisis of 1997–98 in most crisis‐hit countries except Indonesia where high inflation followed a very large nominal depreciation of the rupiah. The high inflation meant a loss of price competitive advantage, a key for economic recovery from a crisis. This paper examines the pass‐through effects of exchange rate changes on the domestic prices in the East Asian economies using a vector autoregression analysis. The main results are as follows: (i) the degree of exchange rate pass‐through to import prices was quite high in the crisis‐hit economies; (ii) the pass‐through to Consumer Price Index (CPI) was generally low, with a notable exception of Indonesia; and (iii) in Indonesia, both the impulse response of monetary policy variables to exchange rate shocks and that of CPI to monetary policy shocks were positive, large, and statistically significant. Thus, Indonesia's accommodative monetary policy, coupled with the high degree of CPI responsiveness to exchange rate changes was an important factor in the inflation‐depreciation spiral in the wake of the currency crisis.     

Noncore Bank Liabilities and Financial Vulnerability

A lending boom is reflected in the composition of bank liabilities when traditional retail deposits (core liabilities) cannot keep pace with asset growth and banks turn to other funding sources (noncore liabilities) to finance their lending. We formulate a model of credit supply as the flip side of a credit risk model where a large stock of noncore liabilities serves as an indicator of the erosion of risk premiums and hence of vulnerability to a crisis. We find supporting empirical evidence in a panel probit study of emerging and developing economies.     

Evidence on the Usefulness of Capital Expenditures as an Alternative Measure of Depreciation

Investment professionals often suggest that accounting earnings is a more useful indicator of share value if adjusted by substituting current capital expenditures for reported depreciation. We investigate the usefulness of this alternative depreciation measure by comparing the ability of reported earnings and adjusted earnings to explain the cross-sectional distribution of stock prices for a large sample of manufacturing firms. We find that adjusted earnings explains a much smaller fraction of the variation in share prices than earnings based on reported depreciation, and provide evidence on the reasons for this difference.     

Exchange market pressure and absorption by international reserves: Emerging markets and fear of reserve loss during the 2008–2009 crisis

This paper evaluates how the global financial crisis emanating from the U.S. was transmitted to emerging markets. Our focus is on the extent that the crisis caused external market pressures (EMP), and whether the absorption of the shock was mainly through exchange rate depreciation or the loss of international reserves. Controlling for variety of factors associated with EMP, we find clear evidence that emerging markets with higher total foreign liabilities, including short- and long-term debt, equities, FDI and derivative products—had greater exposure and were much more vulnerable to the financial crisis. Countries with large balance sheet exposure – high external portfolio liabilities exceeding international reserves—absorbed the global shock by allowing greater exchange rate depreciation and comparatively less reserve loss. Despite the remarkable buildup of international reserves by emerging markets during the period prior to the financial crisis, countries relied primarily on exchange rate deprecation rather than reserve loss to absorb most of the exchange market pressure shock. This could reflect a deliberate choice (“fear of reserve loss”) or market actions that caused very rapid exchange rate adjustment, especially in emerging markets with open capital markets, overwhelming policy actions.     

The U.S. current account deficit and the expected share of world output

We investigate the possibility that the large current account deficits of the U.S. are the outcome of optimizing behavior. We develop a simple long-run world equilibrium model in which the current account is determined by the expected discounted present value of its future share of world GDP relative to its current share of world GDP. The model suggests that under some reasonable assumptions about future U.S. GDP growth relative to the rest of the advanced countries—more modest than the growth over the past 20 years—the current account deficit is near optimal levels. We then explore the implications for the real exchange rate. Under some plausible assumptions, the model implies little change in the real exchange rate over the adjustment path, though the conclusion is sensitive to assumptions about tastes and technology. Then we turn to empirical evidence. A test of current account sustainability suggests that the U.S. is not keeping on a long-run sustainable path. A direct test of our model finds that the dynamics of the U.S. current account—the increasing deficits over the past decade—are difficult to explain under a particular statistical model (Markov-switching) of expectations of future U.S. growth. But, if we use survey data on forecasted GDP growth in the G-7, our very simple model appears to explain the evolution of the U.S. current account remarkably well. We conclude that expectations of robust performance of the U.S. economy relative to the rest of the advanced countries is a contender—though not the only legitimate contender—for explaining the U.S. current account deficit.     

The Great Recession: US dynamics and spillovers to the world economy

This paper provides an empirical investigation of both the within-US and international channels of transmission of macroeconomic and financial shocks by means of a 50-country macroeconometric model (estimated over the 1980-2009 period), including measures of excess liquidity and financial fragility, specifically designed in order to evaluate the relevance of the boom-bust credit cycle view put forward as an interpretation of the recent “Great Recession” episode. We find that such a view is consistent with the empirical evidence. Moreover, concerning the real effects of financial shocks within the US, we detect stronger evidence of an asset prices channel, rather than a liquidity channel. Concerning the spillovers to the world economy, we find that while financial disturbances are transmitted to foreign countries through US house and stock price dynamics, as well as excess liquidity creation, the trade channel is the key trasmission mechanism of real shocks.     

Government finance in the wake of currency crises

We address three questions: (i) Can classical models be reconciled with the fact that many crises are marked by high rates of depreciation and small increases in seignorage revenue? (ii) What are the implications of different financing methods for post-crisis rates of inflation and depreciation? (iii) How do governments pay for the fiscal costs associated with currency crises? To study these questions we use a general equilibrium model in which prospective government deficits trigger a currency crisis. We then use our model in conjunction with fiscal data to interpret government financing in the wake of three recent currency crises: Korea (1997), Mexico (1994) and Turkey (2001).
