Taxes and the Quality of Capital [книги]
Опубликовано на портале: 30-08-2003Austan Goolsbee
This paper shows that tax policy toward investment, by changing the relative prices of capital varieties, can have a direct effect on the quality of capital goods that firms purchase. The empirical results indicate that this impact is economically important and readily apparent in disaggregated data on farming, mining, and construction machinery. The paper also applies a general method for aggregation using index number theory which suggests that all of the investment increase generated by tax subsidies comes from buying higher quality capital goods as opposed to buying a larger number of capital goods. It shows, further, that the supply of capital is upward sloping with an elasticity of about one. The tax induced quality changes documented in the paper imply a tax distortion whose deadweight loss is neglected in the conventional literature but whose magnitude indicates may represent a substantial efficiency cost from capital taxation (or subsidy).

This paper utilizes a unique new dataset of credit card accounts to analyze how people respond to changes in credit supply. The data consist of a panel of thousands of individual credit card accounts from several different card issuers, with associated credit bureau data. We estimate both marginal propensities to consume (MPCs) out of liquidity and interest-rate elasticities. We also evaluate the ability of different models of consumption to rationalize our results, distinguishing the Permanent-Income Hypothesis (PIH), liquidity constraints, precautionary saving, and behavioral models. We find that increases in credit limits generate an immediate and significant rise in debt, counter to the PIH. The average 'MPC out of liquidity' (dDebt/dLimit) ranges between 10%-14%. The MPC is much larger for people starting near their limits, consistent with binding liquidity constraints. However, the MPC is significant even for people starting well below their limit. We show this response is consistent with buffer-stock models of precautionary saving. Nonetheless there are other results that conventional models cannot easily explain, e.g. why so many people are borrowing on their credit cards, and simultaneously holding low yielding assets. Unlike most other studies, we also find strong effects from changes in account-specific interest rates. The long-run elasticity of debt to the interest rate is approximately -1.3. Less than half of this elasticity represents balance-shifting across cards, with most reflecting net changes in total borrowing. The elasticity is larger for decreases in interest rates than for increases, which can explain the widespread use of temporary promotional rates. The elasticity is smaller for people starting near their credit limits, again consistent with liquidity constraints.
A Cure Worse Than the Disease? Currency Crises and the Output Costs of IMF-Supported Stabilization Programs [книги]
Опубликовано на портале: 11-01-2003Michael M. Hutchison
This paper investigates the output effects of IMF-supported stabilization programs, especially those introduced at the time of a severe balance of payments/currency crisis. Using a panel data set over the 1975-97 period and covering 67 developing and emerging-market economies (with 461 IMF stabilization programs and 160 currency crises), authors find that currency crises even after controlling for macroeconomic developments, political and regional factors significantly reduce output growth for 1-2 years. Output growth is also lower (0.7 percentage points annually) during IMF-stabilization programs, but it appears that growth generally slows prior to implementation of the program. Moreover, programs coinciding with recent balance of payments or currency crises do not appear to further damage short-run growth prospects. Countries participating in IMF programs significantly reduce domestic credit growth, but no effect is found on budget policy. Applying this model to the collapse of output in East Asia following the 1997 crisis, we find that the unexpected (forecast error) collapse of output in Malaysia where an IMF-program was not followed-- was similar in magnitude to those countries adopting IMF programs (Indonesia, Korea, Philippines and Thailand).

This paper examines Japanese foreign exchanges interventions from April 1991 to March 2001 based on newly disclosed official data. All the yen-selling (dollar-purchasing) interventions were carried out when the yen/dollar rate was below 125, while all the yen-purchasing (dollar-selling) interventions were carried out when the yen/dollar was above 125. The Japanese monetary authorities, by buying the dollar low and selling it high, have produced large profits, in terms of realized capital gains, unrealized capital gains, and carrying (interest rate differential) profits, from interventions during the ten years. Profits amounted to 9 trillion yen (2% of GDP) in 10 years. Interventions are found to be effective in the second half of the 1990s, when daily yen/dollar exchange rate changes were regressed on various factors including interventions. The US interventions in the 1990s were always accompanied by the Japanese interventions. The joint interventions were found to be 20-50 times more effective than the Japanese unilateral interventions. Japanese interventions were found to be prompted by rapid changes in the yen/dollar rate and the deviation from the long-run mean (say, 125 yen). The interventions in the second half were less predictable than the first half.

Authors review the international finance literature to assess the extent to which international factors affect financial asset demands and prices. International asset pricing models with mean-variance investors predict that an asset's risk premium depends on its covariance with the world market portfolio and, possibly, with exchange rate changes. The existing empirical evidence shows that a country's risk premium depends on its covariance with the world market portfolio and that there is some evidence that exchange rate risk affects expected returns. However, the theoretical asset pricing literature relying on mean-variance optimizing investors fails in explaining the portfolio holdings of investors, equity flows, and the time-varying properties of correlations across countries. The home bias has the effect of increasing local influences on asset prices, while equity flows and cross-country correlations increase global influences on asset prices.
Odious Debt [книги]
Опубликовано на портале: 11-01-2003Michael Kremer, Seema Jayachandran
Some argue that sovereign debt incurred without the consent of the people and not for their benefit, such as that of apartheid South Africa, should be considered odious and not transferable to successor governments. We argue that an institution that truthfully announced whether regimes are odious could create an equilibrium in which successor governments suffer no reputational loss from failure to repay odious debt and hence creditors curtail odious lending. Equilibria with odious lending could be eliminated by amending creditor country laws to prevent seizure of assets for failure to repay odious debt and restricting foreign assistance to countries not repaying odious debt. Shutting down the borrowing capacity of illegitimate regimes can be viewed as a form of economic sanction and has two advantages over most sanctions: it helps rather than hurts the population, and it does not create incentives for evasion by third parties. However, an institution empowered to assess regimes might falsely term debt odious if it favored debtors, and if creditors anticipate this, they would not make loans to legitimate governments. An institution empowered only to declare future lending to a particular government odious would have greater incentives to judge truthfully. A similar approach could be used to reduce moral hazard associated with World Bank and IMF loans.

Our two related goals in this paper are the following: Firstly and mainly, we want to examine the effects of major changes in modelling strategy and econometric methodology, over the past twenty years, on estimation of firm-level investment equations using panel data. Secondly, we try to assess whether the differences in the estimated investment equations, as between recent years and ten to twenty years go in the French and U.S. Manufacturing industries, are real' and economically meaningful. Thus our paper consists of a series of comparisons: a simple accelerator-profit specification versus one with error correction, traditional between- and within-firm estimation versus GMM estimation, the investment behavior of French firms versus that of U.S. firms, and investment behavior in recent years versus ten to twenty years ago. Although the important econometric advances of the past twenty years have been far from being as successful as we had hoped for, we do find some significant improvement in the specification, estimation and interpretation of firm investment equations; we also fin some real changes in the investment behavior of French and U.S. firms during these twenty years.
Martin P. Financial globalization and emerging markets [Текст]. With or without crash? / P. Martin, H. Rey. Cambridge : National Bureau of Economic Research, 2002. 36 p. (NBER working paper series ; 9288 ). [книга]

Authors analyze the impact of financial globalization on asset prices, investment and the possibility of crashes driven by self-fulfilling expectations in emerging markets. In a two-country model with one emerging market (intermediate income level) and one industrialized country (high income level), they show that liberalization of capital flows increases asset prices, investment and income in the emerging market. However, for intermediate levels of international financial transaction costs, authors find that pessimistic expectations can be self-fulfilling, leading to a financial crash. The crash is accompanied by capital flight, a drop in income and investment below the financial autarky level and more market incompleteness. Authors show that emerging markets are more prone to financial crashes simply because they have a lower income level and not because of the existence of market failures (moral hazard or credit constraints), bad monetary policies or exchange rate regimes.

The recently-developed fiscal theory of price level determination contends that there is an important class of policy rules in which there exists a unique rational expectations solution that shows the price level to be dependent upon fiscal policy and independent of monetary variables. The present paper argues, however, that there is an alternative solution to these models that has entirely traditional (or monetarist') properties. This latter solution is perhaps the more plausible since it is the solution that is typically regarded as the bubble-free fundamentals' solution. The argument involves a respecification of feasible instrument variables.

This paper surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three parts. Part I deals with monetary policy in a simply Phillips curve model: it covers credibility issues, political business cycles, and optimal design of monetary institutions. Part II deals with fiscal policy in a dynamic general equilibrium set up: the main topics here are credibility of tax policy, and political determinants of budget deficits. Part III studies economic growth in models with endogenous fiscal policy.

Observed fiscal policy varies greatly across time and countries. How can we explain this variation across time and countries? This paper surveys the recent literature that has tried to answer this question. We adopt a unified approach in portraying public policy as the equilibrium outcome of an explicitly specified political process. We divide the material into three parts. In Part I, we focus on median-voter equilibria that apply to policy issues where disagreement between voters is likely to be one-dimensional. We thus study the general redistributive programs which are typical of the modern welfare state: redistribution between rich and poor, young and old, employed and unemployed, resident of different regions, and labor and capital. In Part II we study special interest politics. Here the policy problem is multi-dimensional and we focus on specific political mechanisms: we study legislative bargaining, lobbying, and electoral competition, as well as the possible interactions between these different forms of political activity. Finally, Part III deals with a set of questions that can be brought under the label of comparative politics. Here we deal with policy choice under alternative political constitutions; we model the rationale for separation of powers and contrast the stylized features of congressional and parliamentary political systems, focusing on their implications for rent extraction by politicians, redistribution and public goods provision.
Do Budget Rules Work? [книги]
Опубликовано на портале: 01-09-2003James Michael Poterba
The design of budget rules and institutions, long a neglected area in public finance and macroeconomics, has recently been thrust to center stage by the debate over a balanced budget amendment and other deficit-reduction measures in the United States. This paper describes the existing evidence on how budget rules affect fiscal policy outcomes. It contrasts the `institutional irrelevance view,' which holds that budget rules can be circumvented by modifying accounting practices and changing the nominal timing or other classification of taxes and expenditures, with the `public choice view' in which fiscal institutions represent important constraints on the behavior of political actors. Several distinct strands of empirical evidence, from the U.S. federal experience with anti-deficit rules, from U.S. state experience with balanced budget rules, and from international comparisons of budget outcomes in nations with different fiscal institutions, suggest that fiscal institutions do matter. These results reject the institutional irrelevance view. The existing evidence is not refined enough, however, to provide detailed advice on how narrowly-defined changes in budget rules might affect policy outcomes.

With many emerging market currencies tied to the U.S. dollar either implicitly or explicitly, movements in the exchange values of the currencies of major countries have the potential to influence the competitive position of many developing countries. According to some analysts, establishing target bands to reduce the variability of the G-3 currencies would limit those destabilizing shocks emanating from abroad. This paper examines the argument for such a target zone strictly from an emerging market perspective. Given that sterilized intervention by industrial economies tends to be ineffective and that policy makers show no appetite to return to the controls on international capital flows that helped keep exchange rates stable over the Bretton Woods era, a commitment to damping G-3 exchange rate fluctuations requires a willingness on the part of G-3 authorities to use domestic monetary policy to that end. Under a system of target zones, then, relative prices for emerging market economies may become more stable, but debt-servicing costs may become less predictable. We use a simple trade model to show that the resulting consequences for welfare are ambiguous. Our empirical work supplements the traditional literature on North-South links by examining the importance of the volatilities of G-3 exchange-rates, and U.S. interest rate and consumption on capital flows and economic growth in developing countries over the past thirty years.
Razin A. A Brazilian debt-crisis model / A. Razin, E. Sadka. Tel Aviv: Tel Aviv University, 2002. (NBER Working Paper; No. 9211). [книга]
Опубликовано на портале: 21-01-2004
Authors develop a model that captures important features of debt crises of the Brazilian type. Its applicability to Brazil lies in the fact that (1) in Brazil the macro fundamentals were sound (e.g., a primary surplus, a relatively low debt/GDP ratio, etc.); and (2) in the Brazilian case the trigger appears to be the forthcoming elections, with an expected regime change.
