Innovation management in organizations

This paper poses the question of how a firm should optimally choose both its organization and its compensation in the pursuit of innovation. One key result is that incentive pay arises as a robust instrument of innovation management both with and without delegation, although in the present model its primary purpose is not to elicit more effort for the creation of new ideas, but to ensure that new ideas are implemented if and only if this is efficient. While without delegation, the firm may “underinvest” in innovation, with delegation the opposite bias may arise as new ideas may be implemented too often (“overinvestment”). The optimal organizational choice trades off these two biases.     

How (not) to pay for advice: A framework for consumer financial protection

This paper investigates the determinants of the compensation structure for brokers who advise customers regarding the suitability of financial products. Our model explains why brokers are commonly compensated indirectly through contingent commissions paid by product providers, even though this compensation structure could lead to biased advice. When customers are wary of the adviser's incentives, contingent commissions can be an effective incentive tool to induce the adviser to learn which specialized product is most suitable for the specific needs of customers. If, instead, customers naively believe they receive unbiased advice, high product prices and correspondingly high commissions become a tool of exploitation. Policy intervention that mandates disclosure of commissions can protect naive consumers and increase welfare. However, prohibiting or capping commissions could have the unintended consequence of stifling the adviser's incentive to acquire information. More vigorous competition benefits consumers and reduces exploitation, but firms have limited incentives to educate naive customers.     

Market selection with learning and catching up with the Joneses

We study the market selection hypothesis in complete financial markets, populated by heterogeneous agents. We allow for a rich structure of heterogeneity: individuals may differ in their beliefs concerning the economy, information and learning mechanism, risk aversion, impatience and ‘catching up with the Joneses’ preferences. We develop new techniques for studying the long-run behavior of such economies, based on Strassen’s functional law of the iterated logarithm. In particular, we explicitly determine an agent’s survival index and show how the latter depends on the agent’s characteristics. We use these results to study the long-run behavior of the equilibrium interest rate and the market price of risk.     

Market‐share contracts as facilitating practices

This article investigates how the use of contracts that condition discounts on the share a supplier receives of a retailer's total purchases (market‐share contracts) may affect market outcomes. The case of a dominant supplier that distributes its product through retailers that also sell substitute products is considered. It is found that when the supplier's contracts can only depend on how much a retailer purchases of its product (own‐supplier contracts), intra‐ and interbrand competition cannot simultaneously be dampened. However, competition on all goods can simultaneously be dampened when market‐share contracts are feasible. Compared to own‐supplier contracts, the use of market‐share contracts increases the dominant supplier's profit and, if demand is linear, lowers consumer surplus and welfare.     

Plant-level nonconvex output adjustment and aggregate fluctuations

In most manufacturing industries plant-level output is adjusted along three margins of capacity utilization: shiftwork, weekend work, and closing temporarily down. Due to the discrete and lumpy nature of these margins, only a fraction of plants adjust output in response to shocks. In a business cycle model calibrated to establishment-level observations, these nonconvexities make aggregate output less volatile than when plants can adjust smoothly. Further, the mass of adjusting plants is larger in downturns than in upturns, leading to counter-cyclical volatility of aggregate output and government policy being slightly more effective in recessions than in expansions.     

Buyer power and mutual dependency in a model of negotiations

We study bilateral bargaining between several buyers and sellers in a framework that allows both sides, in case of a bilateral disagreement, flexibility to adjust trade with each of their other trading partners and receive the gross benefit generated by each adjustment. A larger buyer pays a higher per‐unit price when buyers' bargaining power in bilateral negotiations is sufficiently low, and a lower price otherwise. An analogous result holds for sellers. These predictions, and the implications of different technologies, are explained by the fact that size is a source of mutual dependency and not an unequivocal source of power.

Market power,price discrimination,and allocative efficiency in intermediate‐goods markets

We consider a monopolistic supplier's optimal choice of two‐part tariff contracts when downstream firms are asymmetric. We find that the optimal discriminatory contracts amplify differences in downstream firms' competitiveness. Firms that are larger—either because they are more efficient or because they sell a superior product—obtain a lower wholesale price than their rivals. This increases allocative efficiency by favoring the more productive firms. In contrast, we show that a ban on price discrimination reduces allocative efficiency and can lead to higher wholesale prices for all firms. As a result, consumer surplus, industry profits, and welfare are lower.
