August 2024 - Working Paper32810 Research has shown that the unilateral accumulation of international reserves by a country can improve its own macro-financial stability. However, we show that when many countries accumulate reserves, the induced general equilibrium effects weaken financial and macroeconomic stability, especially...
June 2023 - Working Paper31299 After 162 years of political unification, Italy still displays large regional economic differences. In 2019, the per capita GDP of Lombardia was 39,700 euros, but Calabria's per capita GDP was only 17,300 euros. We build a two-region, two-sector model of the Italian economy to measure the wedges...
January 2023 - Working Paper30832 The sharp, secular decline in the world real interest rate of the past thirty years suggests that the surge in global demand for financial assets outpaced the growth in their supply. We argue that this phenomenon was driven by: (i) faster growth in emerging markets, (ii) changes in the financial...
September 2018 - Working Paper25011 We study how cross-country macroeconomic spillovers caused by sovereign default affect equilibrium bailouts. Because of portfolio diversification, the default of one country causes a macroeconomic contraction in countries that hold its debt, which could justify why a given country may want to...
October 2013 - Working Paper19594 Over the last three decades there has been a dramatic increase in the size of the financial sector and in the compensation of financial executives. This increase has been associated with greater risk-taking and the use of more complex financial instruments. Parallel to this trend, the organizational...
September 2012 - Working Paper18372 This paper investigates whether the international globalization of financial markets allows for significant cross-country risk-sharing at the business cycle frequency. We find that cross-country risk-sharing is still limited and this is unlikely to be the result of financial frictions that limit...
September 2011 - Working Paper17389 We study the importance of financial markets for (un)employment fluctuations in a model with searching and matching frictions where firms issue debt under limited enforcement. Higher debt allows employers to bargain lower wages which in turn increases the incentive to create jobs. The transmission...
July 2011 - Working Paper17201 The 2008-2009 crisis was characterized by an unprecedented degree of international synchronization as all major industrialized countries experienced large macroeconomic contractions around the date of Lehman bankruptcy. At the same time countries also experienced large and synchronized tightening of...
October 2009 - Working Paper15432 Two observations suggest that financial globalization played an important role in the recent financial crisis. First, more than half of the rise in net borrowing of the U.S. nonfinancial sectors since the mid 1980s has been financed by foreign lending. Second, the collapse of the U.S. housing and...
September 2009 - Working Paper15338 In this paper we document the cyclical properties of U.S. firms' financial flows. Equity payouts are procyclical and debt payouts are countercyclical. We develop a model with explicit roles for debt and equity financing and explore how the observed dynamics of real and financial variables are...

It is widely argued that countries can reap large gains from liberalizing their capital accounts if financial globalization is accompanied by the development of domestic institutions and financial markets. However, if liberalization does not lead to financial development, globalization can result in...
September 2007 - Working Paper13412 It is widely argued that countries can reap large gains from liberalizing their capital accounts if financial globalization is accompanied by the development of domestic institutions and financial markets. However, if liberalization does not lead to financial development, globalization can result in...
February 2007 - Working Paper12909 Large and persistent global financial imbalances need not be the harbinger of a world financial crash. Instead, we show that these imbalances can be the outcome of financial integration when countries differ in financial markets deepness. In particular, countries with more advanced financial markets...
August 2006 - Working Paper12474 We study how barriers to competition---such as restrictions to business start-up and strict enforcement of covenants or IPR---affect the investment in knowledge capital when contracts are not enforceable. These barriers lower the competition for human capital and reduce the incentive to accumulate...
June 2006 - Working Paper12308 The volatility of US business cycles has declined during the last two decades. During the same period the financial structure of firms has become more volatile. In this paper we develop a model in which financial factors play a key role in generating economic fluctuations. Innovations in financial...
January 2005 - Working Paper11050 We study a labor market equilibrium model in which firms sign optimal long-term contracts with workers. Firms that are financially constrained offer an increasing wage profile: They pay lower wages today in exchange of higher wages once they become unconstrained and operate at a larger scale. In...
December 2003 - Working Paper10132 We study a general equilibrium model in which entrepreneurs finance investment with optimal financial contracts. Because of enforceability problems, contracts are constrained efficient. We show that limited enforceability amplifies the impact of technological innovations on aggregate output. More...
June 2002 - Working Paper9034 Together with a sense of entering a New Economy, the US experienced in the second half of the 1990s an economic expansion, a stock market boom, a financing boom for new firms and productivity gains. In this paper, we propose an interpretation of these events within a general equilibrium model with...
