Trade and Growth in East Asian Countries: Cause and Effect?

Estimates of growth equations have found a role for openness, particularly in explaining rapid growth among East Asian countries. But major concerns of simultaneous causality between growth and trade have been expressed. This study aims to deal with the endogeneity of trade by using as instrumental variables the exogenous determinants from the gravity model of bilateral trade, such as proximity to trading partners. We find that the effect of openness on growth is even stronger when we correct for the endogeneity of openness than in standard OLS estimates. We conclude with estimates of how much has been contributed to East Asian growth both by the exogenous or geographical component of openness and by the residual or policy component.

Trade and Growth: An Empirical Investigation

Countries' geographic characteristics have important effects on their trade, and are plausibly uncorrelated with other determinants of their incomes. This paper therefore constructs measures of the geographic component of countries' trade and uses those measures to obtain instrumental variables estimates of the effect of trade on income. The results suggest that ordinary least squares estimates understate the effects of trade, and that trade has a quantitatively large, significant, and robust positive effect on income.

Critical Market Crashes

This review is a partial synthesis of the book ``Why stock market crash'' (Princeton University Press, January 2003), which presents a general theory of financial crashes and of stock market instabilities that his co-workers and the author have developed over the past seven years. The study of the frequency distribution of drawdowns, or runs of successive losses shows that large financial crashes are ``outliers'': they form a class of their own as can be seen from their statistical signatures. If large financial crashes are ``outliers'', they are special and thus require a special explanation, a specific model, a theory of their own. In addition, their special properties may perhaps be used for their prediction. The main mechanisms leading to positive feedbacks, i.e., self-reinforcement, such as imitative behavior and herding between investors are reviewed with many references provided to the relevant literature outside the confine of Physics. Positive feedbacks provide the fuel for the development of speculative bubbles, preparing the instability for a major crash. We demonstrate several detailed mathematical models of speculative bubbles and crashes. The most important message is the discovery of robust and universal signatures of the approach to crashes. These precursory patterns have been documented for essentially all crashes on developed as well as emergent stock markets, on currency markets, on company stocks, and so on. The concept of an ``anti-bubble'' is also summarized, with two forward predictions on the Japanese stock market starting in 1999 and on the USA stock market still running. We conclude by presenting our view of the organization of financial markets.Comment: Latex 89 pages and 38 figures, in press in Physics Report

Dualism and Macroeconomic Volatility

This paper develops a simple macroeconomic model that shows that combining capital market imperfections together with unequal access to investment opportunities across individuals can generate endogenous and permanent fluctuations in aggregate GDP, investment, and interest rates. Reducing inequality of access may be a necessary condition for macroeconomic stabilization. Moreover, countercyclical fiscal policies have a role to play: in our model savings are underutilized in slumps because of the limited debt capacity of potential investors. Therefore, the government should issue public debt during recessions in order to absorb those idle savings and finance investment subsidies or tax cuts for investors

Currency depreciation and the monetary adjustment process: Reconsidering Lord King's contributions

© Oxford University Press 2018, All rights reserved. This paper investigates Lord King's contributions in light of the renewed debate on international monetary policy coordination. We argue that King's work contains refined bullionist insights concerning currency depreciation, exchange rate determination, and balance of payments adjustment. We show how King's analysis of the monetary process under different currency regimes can help elucidate the effects of unconventional monetary policy on a global scale, concerning monetary spillovers, currency wars, business cycles, and the distribution of wealth

Social conflict, growth and factor shares

Standard growth theory is based on atomistic agents with no strategic interactions among them. In contrast, we model growth as resulting from a one-off, strategic game between workers and owners of capital (capitalists) on factor shares, in an otherwise standard AK growth model. The resulting distribution of income between factors further determines the marginal revenue product of capital and the rate of growth. We analyse the properties of four equilibria: competitive, Stackelberg equilibrium, a hybrid non-cooperative regime, and cooperative (Nash) solution. We show that our model provides a potentially richer view of the growth process than comparable models, and endogenises a key aspect of the social contract

Government Debt

This paper surveys the literature on the macroeconomic effects of government debt. It begins by discussing the data on debt and deficits, including the historical time series, measurement issues, and projections of future fiscal policy. The paper then presents the conventional theory of government debt, which emphasizes aggregate demand in the short run and crowding out in the long run. It next examines the theoretical and empirical debate over the theory of debt neutrality called Ricardian equivalence. Finally, the paper considers the various normative perspectives about how the government should use its ability to borrow.Economic
