Do timing and time diversification improve the average investor's stock market return? Contrary to literature's scenario of wealthy investors, average investors invest each month over life. Many purchases prevent investors from buying at peak, but horizons decrease, giving latter investments less time to offset losses. This paper accommodates timing using internal rates of return, facilitating the ...

In line with the neoclassical growth model a persistent stream of oil revenues might have a long lasting impact on GDP per capita in oil exporting countries through higher investment activities. This relationship is explored for Iran and the countries of the Gulf Cooperation Council (GCC) using (panel) cointegration techniques. The existence of cointegration between oil revenues, GDP and investment ...

This paper explores the long run relationship between public and private investment in the euro area in terms of capital stocks and gross investment flows. Panel techniques accounting for international spillovers are employed. While private and public capital stocks are cointegrated, the evidence is quite fragile for public and private investment flows. They enter a long run relationship only after ...

How do banks choose their debt maturity structure when credit markets are subject to information frictions? This paper proposes a model of equilibrium maturity choice with asymmetric information and endogenous roll-over risk. We show that in the presence of public signals about firms' creditworthiness (credit ratings), firms choose to expose themselves to positive roll-over risk in order to minimize ...

A canonical two country-two good model with standard preferences does not address three classic international macroeconomic puzzles as well as two well-known asset pricing puzzles. Specifically, under financial autarky, it does not account for the high real exchange rate (RER) volatility relative to consumption volatility (RER volatility puzzle), the negative RER-consumption differentials correlation ...

In this paper, we evaluate the forecasting ability of 115 indicators to predict the housing prices and rents in 71 German cities. Above all, we are interested in whether the local business confidence indicators can allow substantially improving the forecasts, given the local nature of the real-estate markets. The forecast accuracy of different predictors is tested in a framework of a quasi out-of-sample ...

We analyze the transmission of the financial crisis of 2007 to 2009 to 415 country-industry equity portfolios. We use a factor model to predict crisis returns, defining unexplained increases in factor loadings and residual correlations as indicative of contagion. While we find evidence of contagion from the U.S. and the global financial sector, the effects are small. By contrast, there has been substantial ...

This paper investigates the factors influencing banks' decision to engage in advanced risk management, from both a theoretical and an empirical perspective. In recent decades, credit risk management in banks has become highly sophisticated and banks have become more active and advanced in the management of credit risks. We identify two driving factors for risk management: bank competition and sector ...

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which idiosyncratic shocks to bank lending can generate aggregate fluctuations in the credit supply when the banking ...

This paper tests whether an increase in insured deposits causes banks to become more risky. We use variation introduced by the U.S. Emergency Economic Stabilization Act in October 2008, which increased the deposit insurance coverage from $100,000 to $250,000 per depositor and bank. For some banks, the amount of insured deposits increased significantly; for others, it was a minor change. Our analysis ...
