Borders and Growth [статья]
Опубликовано на портале: 14-03-2005
Enrico Spolaore, Romain Wacziarg NBER Working Paper Series. 2002.  No. 9223.
This paper presents a framework to understand and measure the effects of political borders on economic growth and per capita income levels. We present a model providing a theoretical foundation to estimate empirically the effects of political borders on growth. In our model, political integration between two countries results in a positive country size effect and a negative effect through reduced openness vis-…-vis the rest of the world. We estimate the growth effects that would have resulted from the hypothetical removal of national borders between pairs of adjacent countries. We also identify country pairs where political integration would have been mutually beneficial.

International economic integration yields large potential welfare effects, even in a static constant returns competitive world economy. Our method is novel. The effect of border barriers on trade flows is often inferred from gravity models. But their rather atheoretic structure precludes welfare analysis. Computable general equilibrium models are designed for tight welfare analysis, but lack econometric foundation. Our method combines these approaches. Gravity models based on Anderson's (1979) interpretation are full general equilibrium models of a special simple sort. In Anderson and van Wincoop (NBER WP 8079, 2001) we develop and estimate this structure, then calculate the comparative static effects on trade flows of border barriers. In this paper we further deploy the model to explore the comparative statics of welfare with respect to borders, to currency unions and to NAFTA. Our NAFTA exercise does a much better job of replicating the actual trade flow changes than do computable general equilibrium models. An interesting implication is that terms of trade changes are very important, even for small' countries such as Mexico.

This paper deals with some of the most important aspects of Latin America's experience with capital flows during the last twenty-five years. The paper begins with a historical analysis. I then deal with the sequencing of reform and discuss issues related to the relationship between capital flows, real exchange rates, and international competitiveness. I next concentrate on the role of capital controls as a device for isolating emerging economies from the volatility of international capital markets. I begin by reviewing the policy issues and the current debate on the subject. I then present an empirical analysis of Chile's recent experiences with capital controls and make some comparisons to the recent experiences of Columbia. The analysis of the Chilean experience is particularly important since its practice of imposing reserves requirements on capital inflows has been praised by a number of analysts, including senior staff of the multilateral institutions, as an effective and efficient way of reducing the vulnerability associated with capital flows volatility. The results obtained suggest that capital controls in Chile have had mixed results: while they have allowed the Central Bank to have a greater degree of control over short term interest rates, they have failed in avoiding real exchange rate appreciation. The paper ends with some reflections, based on recent Latin American historical episodes, on the role of banks in intermediating capital inflows and on financial crises.

В статье анализируется связь между экзогенными изменениями цен экспортируемого сырья и реальным курсом. Для этого в качестве базовой используется модель "голландской болезни", которая дополнена денежным рынком. В работе показано, что бум на внешнем сырьевом рынке в краткосрочном периоде может привести к чрезмерному как спросу, так и предложению денег. При этом в данной модели поведение реального курса существенно отличается от поведения в традиционной модели "голландской болезни" без денег. Модель тестируется на данных Колумбии, которая в в середине 70-х гг. испытала шок в виде резкого роста цен на кофе.

The difficulty of incorporating general equilibrium price effects into econometric estimating equations has deterred most researchers from econometrically estimating the welfare gains from trade liberalization. Using a paired-down CES monopolistic competition example, autors show that this difficulty has been greatly exaggerated. Along the way, we estimate indeed precisely estimate large welfare gains from trade liberalization as measured by compensating variation. Unlike calibration methods, econometric methods allow researchers to isolate the violence done by the model to the data. Autors find that the CES monopolistic competition model horribly mis-specifies behavioural price elasticities and general equilibrium price feedbacks. The model as conceived is therefore of limited value for analysing the effects of trade liberalization. Autors report a number of specification issues that should point the way to better theoretical modeling.

This paper reviews the behavior of stock prices in relation to consumption. The paper lists some important stylized facts that characterize US data, and relates them to recent developments in equilibrium asset pricing theory. Data from other countries are examined to see which features of the US experience apply more generally. The paper argues that to make sense of stock market behavior one needs a model in which investors' risk aversion is both high and varying, such as the external habit-formation model of Campbell and Cochrane (1995).

В работе проводится обзор теоретических и эмпирических исследований в области базовых механизмов корпоративного управления. Обсуждаются основные правовые и регулирующие институты в различных странах. Акцент делается на следующей фундаментальной дилемме: управление со стороны крупных акционеров может создавать лучшую защиту для мелких акционеров, но данное управление может увеличить степень злоупотреблений со стороны менеджеров.

There is increasing empirical evidence that creative destruction, driven by experimentation and the adoption of new products and processes when investment is sunk, is a core mechanism of development. Obstacles to this process are likely to be obstacles to the progress in standards of living. Generically, underdeveloped and politicized institutions are a major impediment to a well-functioning creative destruction process, and result in sluggish creation, technological sclerosis,' and spurious reallocation. Those ills reflect the macroeconomic consequences of contracting failures in the presence of sunk investments. Recurrent crises are another major obstacle to creative destruction. The common inference that increased liquidations during crises result in increased restructuring is unwarranted. Indications are, to the contrary, that crises freeze the restructuring process and that this is associated with the tight financial-market conditions that follow. This productivity cost of recessions adds to the traditional costs of resource under-utilization.

Debt Intolerance [статья]
Опубликовано на портале: 10-12-2003

This paper introduces the concept of 'debt intolerance,' which manifests itself in the extreme duress many emerging markets experience at debt levels that would seem manageable by advanced country standards. We argue that 'safe' external debt-to-GNP thresholds for debt intolerant countries are low, perhaps as low as 15 percent in some cases. These thresholds depend on a country's default and inflation history. Debt intolerance is linked to the phenomenon of serial default that has plagued many countries over the past two centuries. Understanding and measuring debt intolerance is fundamental to assess the problems of debt sustainability, debt restructuring, capital market integration, and the scope for international lending to ameliorate crises. Our goal is to make a first pass at quantifying debt intolerance, including delineating debtors' clubs and regions of vulnerability, on the basis on a history of credit events going back to the 1820s for over 100 countries.

In this paper I analyze the relationship between fiscal policy, aggregate public sector debt sustainability, and debt relief. I develop a methodology to compute the fiscal policy path that is compatible with aggregate debt sustainability in the post-HIPC era. The model explicitly considers the role of domestic debt, and quantifies the extent to which future debt sustainability depends on the availability of concessional loans at subsidized interest rates. The working of the model is illustrated for the case of Nicaragua, a country that in 2002 had one of the highest net present value of public external debt to GDP ratios.

Debt Restructuring [статья]

What difference does it make, and for whom, whether the nonperforming debts of emerging market borrowers are restructured? This paper begins by positing a set of counterfactual conditions under which restructuring would not matter, and then shows how several ways in which the actual world of international lending departs from these conditions give both lenders and borrowers ample reason to care whether nonperforming debts are restructured. One implication of the way in which debt restructuring matters is that restructuring should not be too' easy. Further, with a greater frequency of defaults, some credit flows to emerging market countries would not be extended in the first place. An important element driving this line of argument is moral hazard, but (unlike in much of the recent literature of emerging market debt problems) what is central here is not the availability of credit from the IMF or other official lenders but the more fundamental moral hazard inherent in all uncollateralized borrower-lender relationships.

This paper examines the robustness of explanatory variables in cross-country economic growth regressions. It employs a novel approach, Bayesian Averaging of Classical Estimates (BACE), which constructs estimates as a weighted average of OLS estimates for every possible combination of included variables. The weights applied to individual regressions are justified on Bayesian grounds in a way similar to the well-known Schwarz criterion. Of 32 explanatory variables we find 11 to be robustly partially correlated with long-term growth and another five variables to be marginally related. Of all the variables considered, the strongest evidence is for the initial level of real GDP per capita.

Optimal tax theory has shown that, under weak assumptions, indirect taxation such as production subsidies, tariffs, or differentiated commodity taxation, are sub-optimal and that redistribution should be achieved solely with the direct income tax. However, these important results of optimal tax theory, namely production efficiency and uniform commodity taxation under non-linear income taxation, have been shown to break down when labor taxation is based on income only and when there is imperfect substitution of labor types in the production function. These results in favor of indirect tax instruments are valid in the short-run when skills are exogenous and individuals cannot move from occupation to occupation. In the long-run, it is more realistic to assume that individuals choose their occupation based on the relative after-tax rewards. This paper shows that, in that context, production efficiency and the uniform commodity tax result are restored. Therefore, in a long-run context, direct income taxation should be preferred to indirect tax instruments to raise revenue and achieve redistribution.

Does leaving a currency union reduce international trade? We answer this question using a large annual panel data set covering 217 countries from 1948 through 1997. During this sample a large number of countries left currency unions; they experienced economically and statistically significant declines in bilateral trade, after accounting for other factors. Assuming symmetry, we estimate that a pair of countries that starts to use a common currency experiences a doubling in bilateral trade.

We show that equity market liberalizations, on average, lead to a one percent increase in annual real economic growth over a five-year period. The liberalization effect is not spuriously accounted for by macro-economic reforms and does not reflect a business cycle effect. Although financial liberalizations further financial development, measures of financial development fail to fully drive out the liberalization effect. The investment/GDP ratio increases post liberalization, with the investment partially financed by foreign capital inducing worsened trade balances. Differentiating across liberalizing countries, a large secondary school enrollment, a small government sector and an Anglo-Saxon legal system tend to enhance the liberalization effect. Finally, the conditional convergence effect is larger once financial liberalization is accounted for.
