Reduced-Rank Identification of Structural Shocks in VARs

This paper integrates imposing a factor structure on residuals in vector autoregressions (VARs) into structural VAR analysis. Identification, estimation and testing procedures are discussed. The paper applies this approach to the well-known problem of studying the effects of monetary policy in open economy VAR models. The use of factor structure in identifying structural shocks is shown to resolve three long-standing puzzles in VAR literature. First, the price level does not increase in response to a monetary tightening. Second, the exchange rate appreciates on impact and then gradually depreciates. Hence, no price level and exchange rate puzzles are found. Third, monetary policy shocks are much less volatile than suggested by standard VAR identification schemes. In addition, the paper suggests that the apparent weak contemporaneous cross-variable responses and strong own responses in structural VARs can be an artifact of identifying assumptions and vanish after imposing a factor structure on the shocks.Vector autoregressions, identification, factor structure, monetary policy

Culture, institutions and democratization.

We construct a model of revolution and transition to democracy under individualistic and collectivist cultures. The main result is that, despite facing potentially more challenging collective action problems, countries with individualistic cultures are more likely to end up adopting democracy earlier than countries with collectivist cultures. Our empirical analysis suggests a strong and robust association between individualistic cultures and average polity scores and durations of democracy, even after controlling for other determinants of democracy emphasized in the literature. We provide evidence that countries with collectivist cultures also are more likely to experience autocratic breakdowns and transitions from autocracy to autocracy

Financial constraints and innovation: Why poor countries don't catchup

We examine micro-level channels of how financial development can affect macroeconomic outcomes like the level of income and export intensity. We investigate theoretically and empirically how financial constraints affect a firm's innovation and export activities, using unique firm survey data which provides direct measures for innovations and firm-specific financial constraints. We find that financial constraints restraint heability of domestically owned firms to innovate and export and hence to catch up to the technological frontiers. This negative effect is amplified as financial constraints force export and innovation activities to become substitutes although they are generally natural complements

Returns to Schooling in Russia and Ukraine: A Semiparametric Approach to Cross-Country Comparative Analysis

n Russia and Ukraine (1985-2002). There has been an increase in returns to schooling in both countries but the increase is much bigger in Russia than in Ukraine. The intriguing question is why returns to schooling in Russia and Ukraine diverged so much over the transition period while the skill composition of employment did not. Our approach in analyzing the sources of cross-country differences in returns to schooling is to compare the Mincerian earnings functions between the two countries and then to employ decomposition techniques. Using semiparametric methods, we construct counterfactual wage distributions for university and secondary school graduates for Ukraine using the distributions of Russian characteristics, returns to characteristics, and unobservables. This allows us to decompose differences in returns to schooling between the two countries due to differences in the labor market returns (price effect), differences in unobservables (residual effect), and differences in the labor force composition (composition effect). We conclude that of these three effects the price effect makes a major contribution to the observed differences in the returns to schooling.http://deepblue.lib.umich.edu/bitstream/2027.42/40105/3/wp719.pd

A Re-Examination of the Border Effect

This paper reexamines the evidence on the border effect, the finding that the border drives a wedge between domestic and foreign prices. We argue that the border effect can be inflated by the volatility and persistence of the nominal exchange rate and by the cross-country heterogeneity in the distribution of within-country price differentials. We develop a simple framework to separate the border effect from these confounding factors. Using price data from Engel and Rogers (1996) and Parsley and Wei (2001), we show that after controlling for the confounding factors the border effect between the U.S. and Canada and the U.S. and Japan is negligible.

Are Oligarchs Productive? Theory and Evidence

This paper develops a partial equilibrium model to account for stylized facts about the behavior of oligarchs, politically and economically strong conglomerates in transition and developing countries. The model predicts that oligarchs are more likely than other owners to invest in productivity enhancing projects and to vertically integrate firms to capture the gains from possible synergies and, thus, oligarchs can be socially beneficial. Using a unique dataset comprising almost 2,000 Ukrainian open joint stock companies, the paper tests empirical implications of the model. In contrast to commonly held views, econometric results suggest that, after controlling for endogeneity of ownership, oligarchs tend to improve the performance of the firms they own relative to other firms.Oligarch, transition, firm performance, property rights, treatment effect
