In this paper we empirically investigate whether changes in product market competition affect firm boundaries — the perennial make-or-buy problem. Exploiting regulation-induced shocks to entry barriers and differences in regulation enforcement across cities to obtain a source of exogenous variation in product-market competition, we establish a negative causal effect of competition (through redu...

Markets quickly converge to equilibrium even under information conditions that are much weaker than specified in theory. Given such conditions, how do firms set prices? We test whether, under weak information conditions, firms employ an aspiration level heuristic for price setting. Analyzing the pricing strategies of 745 used car dealers on the basis of online market data and interviews we find...

This effect is particularly strong for establishments belonging to younger...

We conducted a single arm phase II study to investigate the feasibility and efficacy of addition of bevacizumab and oxaliplatin to preoperative standard RCT with ...
