The wrath of God : macroeconomic costs of natural disasters

The process of global climate change has been associated with an increase in the frequency of climatic disasters. Yet, there is still little systematic evidence on the macroeconomic costs of these episodes. This paper uses panel time-series techniques to estimate the short and long-run impact of climatic and other disasters on a countrys GDP. The results indicate that a climate related disaster reduces real GDP per capita by at least 0.6 percent. Therefore, the increased incidence of these disasters during recent decades entails important macroeconomic costs. Among climatic disasters, droughts have the largest average impact, with cumulative losses of 1 percent of GDP per capita. Across groups of countries, small states are more vulnerable than other countries to windstorms, but exhibit a similar response to other types of disasters; and low-income countries responds more strongly to climatic disasters, mainly because of their higher response to droughts. However, a countrys level of external debt has no relation to the output impact of any type of disaster. The evidence also indicates that, historically, aid flows have done little to attenuate the output consequences of climatic disasters.

The Politics of Financial Development: Evidence from Trade Liberalization

Incumbents in various industries have different incentives to promote or oppose financial development. Changes in the relative strength of promoter and opponent industries thus result in changes in the political equilibrium level of financial development. We conduct an event study using a sample of 41 countries that liberalized trade during 1970 to 2000, and show that the strengthening of promoter relative to opponent industries resulting from liberalization is a good predictor of subsequent financial development. The benefits of developing the financial system are insufficient for financial development, and rents in particular hands appear to be necessary to achieve it.

Credit Chains and Sectoral Comovement: Does the Use of Trade Credit Amplify Sectoral Shocks?

This paper provides evidence of the presence and relevance of a credit-chain amplification mechanism by looking at its implications for the correlation of industries. In particular, it tests the hypothesis that an increase in the use of trade-credit along the input-output chain linking two industries results in an increase in their correlation. The analysis uses detailed data on the correlations and input-output relations of 378 manufacturing industry-pairs across 44 countries with different degrees of use of trade credit. The results provide strong support for this hypothesis and indicate that the mechanism is quantitatively relevant.

How do governments respond after catastrophes ? natural-disaster shocks and the fiscal stance

Natural disasters could constitute a major shock to public finances and debt sustainability because of their impact on output and the need for reconstruction and relief expenses. This paper uses a panel vector autoregressive model to systematically estimate the impact of geological, climatic, and other types of natural disasters on government expenditures and revenues using annual data for high and middle-income countries over 1975-2008. The authors find that, on average budget, deficits increase only after climatic disasters, but for lower-middle-income countries, the increase in deficits is widespread across all events. Disasters do not lead to larger deficit increases or larger output declines in countries with higher initial government debt. Countries with higher financial development suffer smaller real consequences from disasters, but deficits expand further in these countries. Disasters in countries with high insurance penetration also have smaller real consequences but do not result in deficit expansions. From an ex-post perspective, the availability of insurance offers the best mitigation approach against real and fiscal consequences of disasters.

Pension funds and capital market development

This paper studies the relation between institutional investors and capital market development by analyzing unique data on monthly asset-level portfolio allocations of Chilean pension funds between 1995 and 2005. The results depict pension funds as large and important institutional investors that tend to hold a large amount of bank deposits, government paper, and short-term assets; buy and hold assets in their portfolios without actively trading them; hold similar portfolios at the asset-class level; simultaneously buy and sell similar assets; and follow momentum strategies when trading. Although pension funds may have contributed to the development of certain primary markets, these patterns do not seem fully consistent with the initial expectations that pension funds would be a dynamic force driving the overall development of capital markets. The results do not appear to be explained by regulatory restrictions. Instead, asset illiquidity and manger incentives might be behind the patterns illustrated in this paper.

A Note on Enforcement Spending and Vat Revenues

Tax compliance studies usually focus on the effect of enforce-ment spending on tax evasion. Reliable estimates are difficult to obtain because evasion data are often suspect. This note shows how tax revenues can be used instead of evasion data to estimate the impact of changes in enforcement spending. Applying our method to Chilean data, we find that 1 (USD) of additional enforcement spending increases VAT revenues by 31. Moreover, current levels of spending could increase by 40 and still be within sample values. Hence, a 10 increase in spending could reduce evasion from its current rate of 23 to 20.

Over the hedge : exchange rate volatility, commodity price correlations, and the structure of trade

A long empirical literature has examined the idea that, in the absence of hedging mechanisms, currency risk should have an adverse effect on the export volumes of risk averse exporters. But there are no clear conclusions from this literature, and the current consensus seems to be that there is at most a weak negative effect of exchange rate volatility on aggregate trade flows. However, most of this literature examines the impact of exchange rate volatility on aggregate trade flows, implicitly assuming a uniform impact of this volatility on exporters across sectors. This paper explots the fact that, if exchange rate volatility is detrimental for trade, firms exporting goods that offer a natural hedge against exchange rate fluctuations -- i.e. those whose international price is negatively correlated with the nominal exchange rate of the country where they operate -- should be relatively benefited in environments of high exchange rate volatility, and capture a larger share of the countrys export basket. This hypothesis is tested using detailed data on the composition of trade of 132 countries at 4-digit SITC level. The results show that the commodities that offer natural hedge capture a larger share of a countrys export basket when the exchange rate is volatile, but there is only weak evidence that the availability of financial derivatives to hedge currency risk reduces the importance of a sectors natural hedge.

Banking on Politics

This paper presents new data from 150 countries showing that former cabinet members, central bank governors, and financial regulators are many orders of magnitude more likely than other citizens to become board members of banks. Countries where the politician-banker phenomenon is more prevalent have higher corruption and more powerful yet less accountable governments, but not better functioning financial systems. Regulation becomes more pro-banker where this happens more often. Furthermore, a higher fraction of the rents that are created accrue to bankers, former politicians are not more likely to be directors when their side is in power, and banks are more profitable without being more leveraged. Rather than supporting a public interest view, the evidence is consistent with a capture-type private interest story where, in exchange for a non-executive position at a bank in the future, politicians provide for beneficial regulation.

Multilateral Debt Relief through the Eyes of Financial Markets

This paper conducts an event study of the impact of multilateral debt relief initiatives announcements on the stock prices of South African companies with subsidiaries in countries benefited by these initiatives. It shows that these prices increase significantly above those of other firms, especially around the launching of the Multilateral Debt Relief Initiative. These price increases are consistent with lower expected levels of future taxation in the benefited countries and provide evidence of the economic consequences of multilateral debt relief that is robust to reverse causality between economic performance and the decision to grant debt relief.

Monetary policy and sectoral shocks : did the Federal Reserve react properly to the high-tech crisis?

The authors present an identification strategy that allows them to study the sectoral effects of monetary policy and the role that monetary policy plays in the transmission of sectoral shocks. They apply their methodology to the case of the United States and find some significant differences in the sectoral responses to monetary policy. They also find that monetary policy is a significant source of sectoral transfers. In particular, a shock to equipment and software investment, which one identifies with the high-tech crisis, induces a response by the monetary authority that generates a temporary boom in residential investment and durables consumption but has almost no effect on the high-tech sector. Finally, the authors perform an exercise evaluating the models predictions about the automatic and more aggressive monetary policy response to a shock similar to the one that hit the United States in early 2001. They find that the actual drop in interest rates is in line with the predictions of the model.
