We ask why, in many circumstances and many environments, decision-makers choose to act on a time-regular basis (e.g. adjust every six weeks) or on a state-regular basis (e.g. set prices ending in a 9), even though such an approach appears suboptimal. The paper attributes regular behaviour to...

This paper documents the patterns and determinants of price setting in the Belgian industry. We analyse the micro data underlying the Producer Price Index (PPI) over the period from February 2001 to January 2005. On average only one out of four prices changes in a typical month, whereas the...

Suppose a fund manager uses predictors in changing port-folio allocations over time. How does predictability translate into portfolio decisions? To answer this question we derive a new model within the Bayesian framework, where managers are assumed to modulate the systematic risk in part by...

Yield curves built from liquid instruments tend to exhibit specific features, both in term of smoothness and in term of patterns. The paper presents empirical evidence that those liquid yiled curves frequently conform to a specific functional form. This specific functional form is predicted by a...

We show that limited dealer participation in the market, coupled with an informational friction resulting from high frequency trading, can induce demand for liquidity to be upward sloping and strategic complementarities in traders' liquidity consumption decisions: traders demand more liquidity...

A growing body of literature analyses the impact of news on companies' equity prices. We add to this literature by showing that the transmission channel of news to prices differs across sectors. First, we disentangle sectoral equity prices into components of expected future earnings and equity...

This paper documents a durable increase in the cross-sectoral dispersion of earnings expectations during the COVID-19 crisis. The rise in dispersion of earnings forecasts can be explained by the introduction of lockdown measures, which had a particularly adverse impact on the travel sector....

We propose a new model of trading in OTC markets. Dealers accumulate inventories by trading with end-investors and trade among each other to reduce their inventory holding costs. Core dealers use a more efficient trading technology than peripheral dealers, who are heterogeneously connected to...
