Review of “This Time is Different: Eight Centuries of Financial Folly by Carmen M. Reinhart and Kenneth S. Rogoff”

This Time is Different: Eight Centuries of Financial Folly is one of the best, if not the best, books ever written on the history of financial crises. It presents a comprehensive survey of financial crises utilizing an extraordinary database of macroeconomic and financial series. The massive data analysis constituting the core of the manuscript leads the authors to arrive at a simple but powerful conclusion: while times change, locations change, actors change, financial crises often exhibit more similarities than differences throughout history. This conclusion nicely relates to the title of the book as it proves wrong the claim “this time is different” that is often heard during boom times preceding crises. The book is a must read for anyone interested in economics and finance. This review presents a brief summary of the book and a discussion about its implications for future research.

Small Countries and Preferential Trade Agreements "How Severe is the Innocent Bystander Problem?"

This paper examines the welfare implications of preferential trade agreements (PTAs) from the perspective of small countries in the context of a multi-country, general equilibrium model. We calibrate our model to represent one relatively small country and two symmetric big countries. We consider two cases. In one case, the small country is an 'innocent bystander', that is, it is left out of a PTA between the two large countries. In the second case, the small country signs a PTA with one of the large countries. We simulate the model and calculate consumption allocations, prices, t rade volume, and tariffs in these two cases considering three different equilibria: Free Trade (FT), Free Trade Area (FTA), and Customs Union (CU). We find that free trade is the best outcome for the small country. If the large country PTA takes the for m of a CU then the cost of being an 'innocent bystander' is very large. If it is a FTA then the cost of being an 'innocent bystander' is relatively modest. In fact, the small country prefers to be an 'innocent bystander' to being a member of a FTA with one of the large countries.Preferential trade agreements, general equilibrium, tariffs, welfare, small countries

Can the standard international business cycle model explain the relation between trade and comovement?

Recent empirical research finds that pairs of countries with stronger trade linkages tend to have more highly correlated business cycles. We assess whether the standard international business cycle framework can replicate this intuitive result. We employ a three-country model with transportation costs. We simulate the effects of increased goods market integration under two asset market structures: complete markets and international financial autarky. Our main finding is that under both asset market structures the model can generate stronger correlations for pairs of countries that trade more, but the increased correlation falls far short of the empirical findings. Even when we control for the fact that most country pairs are small with respect to the rest of the world, the model continues to fall short. We also conduct additional simulations that allow for increased trade with the third country or increased TFP shock comovement to affect the country pair’s business cycle comovement. These simulations are helpful in highlighting channels that could narrow the gap between the empirical findings and the predictions of the model.Business cycles ; International trade

Thresholds in the Process of International Financial Integration

The financial crisis has re-ignited the fierce debate about the merits of financial globalization and its implications for growth, especially for developing countries. The empirical literature has not been able to conclusively establish the presumed growth benefits of financial integration. Indeed, a new literature proposes that the indirect benefits of financial integration may be more important than the traditional financing channel emphasized in previous analyses. A major complication, however, is that there seem to be certain "threshold" levels of financial and institutional development that an economy needs to attain before it can derive the indirect benefits and reduce the risks of financial openness. In this paper, we develop a unified empirical framework for characterizing such threshold conditions. We find that there are clearly identifiable thresholds in variables such as financial depth and institutional quality − the cost-benefit trade-off from financial openness improves significantly once these threshold conditions are satisfied. We also find that the thresholds are lower for foreign direct investment and portfolio equity liabilities compared to those for debt liabilities.financial openness, capital account liberalization, growth, threshold conditions, financial development, institutions, macroeconomic policies

Recessions and Financial Disruptions in Emerging Markets: A Bird´s Eye View.

This paper provides an overview of the implications of recession and financial disruption episodes in emerging markets. We report three major findings. First, compared to advanced countries, recessions and financial disruptions in emerging markets are often more costly. Second, recessions associated with financial disruption episodes, such as credit crunches, equity price busts and financial crises, tend to be deeper than other recessions in emerging markets. Third, the temporal dynamics of macroeconomic and financial variables around these episodes in emerging markets are different than those in advanced countries. In light of these broad observations, the paper provides a review of recessions and financial market disruptions in Chile

The trade comovement problem in international macroeconomics

Recent empirical research finds that pairs of countries with stronger trade linkages tend to have more highly correlated business cycles. We assess whether the standard international business cycle framework can replicate this intuitive result. We employ a three-country model with transportation costs. We simulate the effects of increased goods market integration under two asset market structures: complete markets and international financial autarky. Our main finding is that under international financial autarky the model can generate stronger correlations for pairs of countries that trade more, but the increased correlation falls far short of the empirical findings. In our benchmark calibrations, the model explains at most 6 percent of the responsiveness of GDP correlations to trade found in the empirical research. This result is robust to many combinations of shock specifications, import shares, and elasticities of substitution. Because the difference between business cycle theory and the empirical results cannot be resolved by changes in parameter values and the structure of the standard models, we call this discrepancy the trade comovement problem

Does Openness to International Financial Flows Contribute to Productivity Growth?

Economic theory has identified a number of channels through which openness to international financial flows could raise productivity growth. However, while there is a vast empirical literature analyzing the impact of financial openness on output growth, far less attention has been paid to its effects on productivity growth. This paper provides a comprehensive analysis of the relationship between financial openness and total factor productivity (TFP) growth using an extensive dataset that includes various measures of productivity and financial openness for a large sample of countries. We find that de jure capital account openness has a robust positive effect on TFP growth. The effect of de facto financial integration on TFP growth is less clear, but this masks an important and novel result. We find strong evidence that FDI and portfolio equity liabilities boost TFP growth while external debt is actually negatively correlated with TFP growth. The negative relationship between external debt liabilities and TFP growth is attenuated in economies with higher levels of financial development and better institutions.foreign direct investment, external assets and liabilities, capital flows, capital account liberalization, financial openness, portfolio equity, debt, total factor productivity

Understanding the welfare implications of preferential trade agreements

This paper examines various implications of Preferential Trade Agreements (PTAs), namely Customs Unions (CUs) and Free Trade Areas (FTAs), in the context of a multi-country general equilibrium model based on comparative advantage considerations. We calibrate the model to represent countries with symmetric endowments, and compare the impact of those agreements with free trade and a non-cooperative Nash equilibria. Utilizing aggregate and disaggregate welfare change measures, we quantify the welfare effects of trade arrangements. In particular, we develop a numerical approximation procedure to decompose the welfare changes into two components associated with the variations in terms of trade and volume of trade. The results of our analysis indicate that FTAs are better than CUs on welfare grounds for the world as a whole since both member and nonmember economies enjoy welfare benefits in an FTA. Further, we show that, for certain endowment distributions, upon formation of an FTA, nonmember economies get larger welfare benefits than member economies do. Nonetheless, member economies have larger welfare gains in CUs than in FTAS. Our welfare decompositions suggest that a significant fraction of the welfare changes in both member and nonmember countries is explained by the volume of trade effect for both types of PTAS. This implies that, having free access to larger markets, along with greater market power are both important aspects of PTAS. Comparison across endowment distributions indicates that as countries become more divergent in their endowments, the volume of trade effect gets more pronounced for CUs as well as for FTAS. The absence of policy coordination between the members of FTAs decreases the market power of the member economies and induces welfare losses that are associated with the terms of trade effect. However, the ten-ns of trade effect results in significant welfare gains for the members of CUs since they jointly determine their tariff rates

Trade shocks and macroeconomic fluctuations in Africa

This paper examines the role of external shocks in explaining macroeconomic fluctuations in African countries. We construct a quantitative, stochastic, dynamic, multi-sector equilibrium model of a small open economy calibrated to represent a typical African economy. In our framework, external shocks consist of trade shocks, modeled as fluctuations in the prices of exported primary commodities, imported capital goods and intermediate inputs, and a financial shock, modeled as fluctuations in the world real interest rate. Our results indicate that while trade shocks account for roughly 45 percent of economic fluctuations in aggregate output, financial shocks play only a minor role. We also find that adverse trade shocks induce prolonged recessions
