The estimation of large Vector Autoregressions with stochastic volatility using standard methods is computationally very demanding. In this paper we propose to model conditional volatilities as driven by a single common unobserved factor. This is justified by the observation that the pattern of...

We construct a unique dataset of legislative reforms in merger control legislation that occurred in nineteen industrial countries in the period 1987-2004, and investigate the economic impact of these changes on stock prices. In line with the hypothesis that merger control should challenge...

The paper reconsiders the conflicting results in the debate connected to the effects of technology shocks on hours worked in the bivariate system. Given major dissatisfaction with the just-identifying long-run restrictions, I analyze whether the restrictions used in the literature are consistent...

Forecast models that take into account unbalanced datasets have recently attracted substantial attention. In this paper, we focus on different methods pro- posed so far in the literature to deal with mixed-frequency and ragged-edge datasets: bridge equations, mixed-data sampling (MIDAS), and...

Out-of-sample tests of forecast performance depend on how a given data set is split into estimation and evaluation periods, yet no guidance exists on how to choose the split point. Empirical forecast evaluation results can therefore be di cult to interpret, particularly when several values of...

We provide a comprehensive review of firms’ financing channels (internal and external, domestic and international) around the globe, with the focus on alternative finance—financing from all the nonmarket, non-bank external sources. We argue that while traditional financing channels,...

Most analyses of banking crises assume that banks use real contracts. However, in practice contracts are nominal and this is what is assumed here. We consider a standard banking model with aggregate return risk, aggregate liquidity risk and idiosyncratic liquidity shocks. We show that, with...

With extensive country- and firm-level data sets we first document that the financial sectors of most sub-Saharan African countries remain significantly underdeveloped by the standards of other developing countries. We also find that population density appears to be considerably more important...

In this paper we examine the competitive equilibria of a dynamic stochastic economy with complete markets and collateral constraints. We show that, provided both the set of asset payoffs and collateral levels are sufficiently rich, the equilibrium allocations with sequential trades and...

We study a model of occupational choice where workers must rely on their social contacts to acquire job vacancy information. Contrary to the existing literature, we allow for worker heterogeneity in terms of their idiosyncratic skill-types. In this case, the allocation of talent (the matching of...
