This paper considers the effect of different firm leadership on the innovative performance of firms from seven EU countries. We investigate whether owner-led or manager-led firms achieve a larger share of their turnover with product innovations. Economic theory does not propose clear answers to this question. In the empirical analysis, it turns out that the manager-led firms are more active inn...
A budget-constrained buyer wants to purchase items from a shortlisted set. Items are differentiated by quality and sellers have private reserve prices for their items. Sellers quote prices strategically, inducing a knapsack game. The buyer’s problem is to select a subset of maximal quality. We propose a buying mechanism which can be viewed as a game theoretic extension of Dantzig’s greedy heuri...
We examine the response of Medicare Advantage contracts to published quality ratings. We identify the effect of star ratings on premiums using a regression discontinuity design that exploits plausibly random variation around rating thresholds. We find that 3, 3.5, and 4-star contracts in 2009 significantly increased their 2010 monthly premiums by $20 or more relative to contracts just below the...
In this paper, we reconsider the appropriateness of certain statistical analyses in innovation adoption studies and suggest that partial observability models may sometimes be more useful. The proposed models allow for a flexible specification of the process of adoption from one stage to two stages, facilitate the modelling of non-adopters and remedy the violation of the assumption of full infor...
In a diffusion model of an enterprise with variable scale, conditions are given for the maximization of ‘profit’ (expected total discounted withdrawals) to lead to bankruptcy almost surely. The optimal withdrawal policy is an ‘overflow policy’: the withdrawal rate is zero if the asset level is below a ‘barrier’, and equal to the maximum rate if the asset level is at least equal to the barrier. ...
We study a firm in which the marginal productivity of agents’ effort increases with the effort of others. We show that the presence of an agent who overestimates his marginal productivity may make all agents better off, including the biased agent himself. This Pareto improvement is obtained even when compensation contracts are set endogenously to maximize firm value. We show that the presence o...
One-shot interaction and repeated interaction often co-exist in the real world. We study possible behavioral effects of this co-existence in a principal-agent setting, in which a principal simultaneously employs a permanent and a temporary agent. Our experimental results indicate that there is “discrimination” between the two agents and that the available information for agents determines the e...
I consider an oligopoly model where, prior to price competition, firms invest in persuasive advertising and induce brand loyalty in consumers who would otherwise buy the cheapest alternative on the market. This setting, in which persuasive advertising is introduced to homogenous product markets, provides an alternative explanation for price dispersion phenomena. Despite ex-ante symmetry, the eq...

Enclosure experiments with all combinations of NH4 and PO4 treatments were carried out in the northern Baltic coastal zone during the post–spring bloom growth season. Empirical models were used to identify the important 3d treatment effects on the state and process variables governing the main plankton compartments. Moreover, dilution experiments revealed the main nutrient sources for algal gro...
