We analyze the optimal trading and ownership policy of a large shareholder who must trade off diversification and monitoring incentives. Without commitment, the problem is similar to durable goods monopoly: the share price today depends on expected future trades. We show that the large...

In this paper, we study the drivers of permanent and transitory deposit dollarization for a sample of CESE countries using panel cointegration techniques. The results suggest that a positive cointegration relationship exists between permanent dollarization and Minimum Variance Portfolio (MVP)...

In accordance with Basel Capital Accords, the Capital Requirements (CR) for market risk exposure of banks is a nonlinear function of Value-at-Risk (VaR). Importantly, the CR is calculated based on a bank's actual portfolio, i.e. the portfolio represented by its current holdings. To tackle...
