Channel design,coordination, and performance: Future research directions

The marketing literature has made significant progress toward a better understanding of how firms can effectively design and manage their channels of distribution. However, the complexity of today’s channel systems raises additional issues that remain unaddressed. The purpose of this article is to suggest promising research directions in this domain. We suggest several possible avenues to relate multiple channel design and management to channel-system, channel-relationship, and customer-level outcomes. In particular, we see a great opportunity to integrate multichannel customer management and traditional channel design research. We argue that future research should account for cross-level effects and incorporate variables at more than one relationship level.     

Trading and enforcing patent rights

We study how the market for innovation affects enforcement of patent rights. We show that patent transactions arising from comparative advantages in commercialization increase litigation, but trades driven by advantages in patent enforcement reduce it. Using data on trade and litigation of individually owned patents in the United States, we exploit variation in capital gains tax rates across states as an instrument to identify the causal effect of trade on litigation. We find that taxes strongly affect patent transactions, and that trade reduces litigation on average, but the impact is heterogeneous. Patents with larger potential gains from trade are more likely to change ownership, and the impact depends critically on transaction characteristics.     

Primates’ fertilization systems and the evolution of the human brain

Since the time of Darwin and Wallace, the origin of the human brain has been a controversial issue in evolutionary biology. The development of the human brain has been a matter of dispute between those who attribute it to the forces of natural selection and those who emphasize the role of sexual selection. Building on Darwin’s original insights, in this paper we argue that the uniquely human cognitive capabilities are likely to have been initially spurred by sexual selection. We consider the incentive properties of fertilization systems and, pursuing this ‘economic’ perspective, we compare human gender relations with those of other primates. We argue that, because of its potential egalitarian nature and its consequent quasi-monogamic gender relationships, the human fertilization system is much more likely to have given selective advantages to investments in emotional and rational intelligence, thus favoring the development of many fundamental human capabilities. Even if our brain was initially spurred by sexual selection, after some time, unlike the famous case of the peacock’s tail, it proved extremely useful also in the domain of natural selection. Thus, differently from explanations based on the effects of either natural or sexual selection alone, we show that favorable selection complementarities may have had a crucial role in the evolution of the human brain.      

A biased firm in a market with complementary products. A note on the welfare effects

We analyse a duopoly setting with complementary products, in which a firm has a bias about its absolute advantage. We show that the bias can internalize parts of the negative externality that the complementarity of goods creates implying a higher producer's surplus. Moreover, we analyse additional conditions, which lead to an increase in the consumer's surplus. Counterintuitively, we show that the presence of a bias can lead to a positive welfare effect.     

Marijuana and alcohol: Evidence using border analysis and retail sales data

We use retail scanner data on purchases of alcoholic beverages across US counties for 2006 to 2015 to study the link between medical marijuana laws (MMLs) and alcohol consumption. To do this, we exploit differences in the timing of marijuana laws among states and find that they are substitutes. We show that unlike traditional national-level analysis, focusing on contiguous-border county pairs provides unbiased estimates of the effect of MMLs on alcohol sales. Specifically, alcohol sales in counties located in MML states decreased by 12.4%. Results are robust to including placebo effective dates for MMLs in treated states.     

Robust optimization of conditional value at risk and portfolio selection

This paper deals with a portfolio selection model in which the methodologies of robust optimization are used for the minimization of the conditional value at risk of a portfolio of shares.     

Managerial hedging,equity ownership,and firm value

Suppose risk‐averse managers can hedge the aggregate component of their exposure to firm's cash‐flow risk by trading in financial markets but cannot hedge their firm‐specific exposure. This gives them incentives to pass up firm‐specific projects in favor of standard projects that contain greater aggregate risk. Such forms of moral hazard give rise to excessive aggregate risk in stock markets. In this context, optimal managerial contracts induce a relationship between managerial ownership and (i) aggregate risk in the firm's cash flows, as well as (ii) firm value. We show that this can help explain the shape of the empirically documented relationship between ownership and firm performance.
