For instrumental-variable estimation using binary instruments, we offer simple methods to obtain policy-relevant insights beyond local average treatment effects. We demonstrate the methods by evaluating an element of choice introduced into active labour market policy in Germany by a reform in...

When agents do not know where to find a match, they search. However, agents could direct their search to agents who strategically choose a certain signal. Introducing cheap talk to a model of sequential search with bargaining, we find that signals will be truthful if there are mild...

In a model of sequential search with transferable utility, we allow heterogeneous agents to strategically choose a costless signal of their type. Search frictions are included as discounting and explicit search costs. Through signals, if only they are truthful, agents can avoid the...

We model signalling in two-sided sequential search with heterogeneous agents and transferable utility. Search via meetings is time-consuming and thereby costly due to discounting. Search via signals is costless, so that agents can avoid almost all search costs if only the signals are truthful....

"We revisit the puzzling finding that labour market performance appears to deteriorate, as suggested by negative time trends in empirical matching functions. We investigate whether these trends simply arise from omitted variable bias. Concretely, we consider the omission of job seekers beyond...

"The matching of likes is a frequently observed phenomenon. However, for such assortative matching to arise in a search model, often implausibly strong conditions are required. This paper shows that, once signals are introduced, a search model can generate even perfect assortative matching under...

In 1966, the irrigation community in Mula (Murcia, Spain) switched from a market (auction), which had been in place in the town for over 700 years, to a system of fixed quotas with a ban on trading, to allocate water from the town's river. We present a model, in which farmers face liquidity...

I use the term structure model in Cochrane and Piazzesi (2008) and construct currency market prices. The implied currency market prices are counterfactually volatile and predictable, at least with respect to commonly used predictor variables. Getting the model closer to currency market data...
