We develop a new methodology to measure conditional dependency between time series each driven by complicated marginal distributions. We achieve this by using copula functions that link marginal distributions, and by expressing the parameter of the copula as a function of predetermined...

We investigate the consequences for value-at-risk and expected short-fall purposes of using a GARCH filter on various mis-specified processes. We show that careful investigation of the adequacy of the GARCH filter is necessary since under mis-specifications a GARCH filter appears to do more harm...

We evaluate how deviations from normality may affect the allocation of assets. A Taylor expansion of expected utility allows us to focus on certain moments and to compute numerically the optimal portfolio allocation. A decisive advantage of our approach is that it remains operational even if a...

We evaluate how departure from normality may affect the conditional allocation of wealth. The expected utility function is approximated by a forth-order Taylor expansion that allows for non-normal returns. Market returns are characterized by a joint model that captures the time dependency and...

This paper examines what influences Russian households’ decisions to save and borrow. We use the 2008 data from the 17th round of the Russia Longitudinal Monitoring Survey (RLMS-HSE). Our results show that the determinants of saving and borrowing are not only those suggested by economic theory...

A number of researchers have studied the effect of social networks on student academic performance, but the results are not only contradictory but also limited by the use of self-reported estimations of social network use. This paper overcomes this problem, however, as we collect unique data on...

The introduction of institutions of credit information sharing – private credit bureaus and public credit registries – in the market for bank loans represents a possible solution of the information asymmetry problem which most creditors face. However, the possibility of information sharing...

This article estimates stochastic volatility jump-diffusion processes using the continuous empirical characteristic function method based on the Joint characteristic function and the Marginal characteristic function. The emphasis is on the specification of jumps in the asset log-price. Out of...

Market discipline is usually studied in the retail or the corporate deposit markets, while the interbank loan market is disregarded. Banks' abilities to exert market discipline are taken for granted, as they are expected to have the expertise to assess correctly the riskiness of other banks....

This paper investigates how combining positions between the board of directors and top-management affects bank profitability. We use 2010 bank-level data from 112 countries. Our results suggest that combining positions reduces both ROE and ROA of banks. However, for banks in developing...
