Technical note:: Hybrid corn: Its adoption revisited

The analysis presented is for the adoption of hybrid corn. Among the three functional relationships that are tried the log logistic performs best in terms of explanation (R²) and serial correlation before adjusting for it. After adjusting for the serial correlation using the Cochrane Orcutt procedure the differences between the three functional forms practically vanish. The adoption parameter of the log logistic is best explained by economic variables among which the total area of corn in the state, which stands for both the importance in the economy and economies of scale of extension services, is outstanding.     

Revenge, Tax Informing, and the Optimal Bounty

A common belief is that the IRS pays tax informants 10% of whatever their tips produce in revenue. Actually, the bounty rate is even lower, averaging, in recent years, less than 2% of the amount of taxes and fines recovered. Why is it that the IRS is so tightfisted in rewarding informants who help recover taxes that otherwise would not have been recovered? The present paper approaches this question from an economic perspective, introducing a simple model of the informing decision, the implications of which are incorporated into the tax administration's problem of selecting a bounty rate, as well as a probability of convicting informed‐upon evaders, that maximize its expected net revenues from tax informing. The paper shows that a revenue‐maximizing tax administration would set its bounty rate lower and its prosecution efforts higher, the stronger, at the margin, informants' desire to get revenge on former parties with whom they have quarreled. While the IRS may be guided by ethical and moral considerations in designing its bounty scheme, it nevertheless behaves as if it were cynically exploiting informants' emotional drives, cutting down on their fair share in the recovered amounts to help finance its efforts in prosecuting informed‐upon evaders.     

Capture,governance, and resilience: strategy implications from the history of Rome

Organizational resilience is a subject of great interest to management and strategy scholars. Drawing on over 1,000 years of historical data on the Republic of Rome, and focusing primarily on the period of its establishment (509 BC–338 BC), we identify two generic strategies, capture and governance, that together are essential for organizational resilience. Capture strategy relates to market expansions, while governance strategy refers to the capacity of an organization to assimilate, retain, defend, and increase its dominance within annexed markets. The history of Rome also reveals four supporting tactics—saving power, maintaining a stronghold base, isolating and weakening adversaries, and creating forward outposts—that shore up and reinforce the capture and governance strategies, to create a more enduring and resilient enterprise. Interestingly, a system‐wide view of the strategy‐tactic framework also offers insights on resilience through smallness, thus illustrating its conceptual utility to organizations of all sizes including small enterprises.

Marketing insights from text analysis

Language is an integral part of marketing. Consumers share word of mouth, salespeople pitch services, and advertisements try to persuade. Further, small differences in wording can have a big impact. But while it is clear that language is both frequent and important, how can we extract insight from this new form of data? This paper provides an introduction to the main approaches to automated textual analysis and how researchers can use them to extract marketing insight. We provide a brief summary of dictionaries, topic modeling, and embeddings, some examples of how each approach can be used, and some advantages and limitations inherent to each method. Further, we outline how these approaches can be used both in empirical analysis of field data as well as experiments. Finally, an appendix provides links to relevant tools and readings to help interested readers learn more. By introducing more researchers to these valuable and accessible tools, we hope to encourage their adoption in a wide variety of areas of research.

     

Junk-food,home cooking,physical activity and obesity: The effect of the fat tax and the thin subsidy

In an effort to reduce the growing prevalence of obesity, a tax on junk-foods, known as ‘fat tax’, has been proposed, the revenue from which could be used to finance a ‘thin subsidy’ for healthy foods or exercising equipment. The present paper addresses the fat tax and thin subsidy within a food-intake rational-choice model. Assuming that healthy meals are cooked at home with purchased ingredients and time input, the paper examines the effects on obesity of a tax on junk-food meals and a subsidy to cooking ingredients, distinguishing between a weight-conscious and a non-weight conscious individual, and between a weight-conscious individual who is physically active and physically inactive. The results show that for a non-weight conscious individual a fat tax will unambiguously reduce obesity, whereas a thin subsidy may increase obesity. However, for a weight-conscious individual, particularly one who is physically active, even a fat tax may increase obesity, as it may reduce not just the consumption of junk-food, but also the time devoted to physical activity. The paper explores conditions under which obesity will rise, fall, or remain intact following the introduction of a fat tax or a thin subsidy.     

Trademark infringement and optimal monitoring policy

The paper addresses a trademark infringer who seeks to capitalize on the reputation of a trademark owner, sells an identical product under a trademark which is confusingly similar to that of the owner, charges the same price and competes with him in the same market. We show that the welfare-maximizing monitoring intensity is zero, hence the government is not likely to engage in monitoring infringement. Recognizing this, the trademark owner may consider monitoring the market himself, discovering, however, that this is worth his while only if the penalty for infringement, which he fully collects, is sufficiently high. Given the entry condition, an increase in the penalty may either raise or lower the optimal monitoring intensity. In the former case it will counter-intuitively increase the infringer's expected profit, apparently because a higher penalty will also lead to a raise in price. While monitoring enables the trademark owner to maintain a positive profit level, it reduces social welfare. The government may intervene to eliminate the private incentive for monitoring through taxing the collected penalty.     

Factor market rivalry and interindustry competitive dynamics

We study competitive dynamics by using 10 years of data from the biotech industry on patent infringement lawsuits because they capture offensive actions and defensive responses. Results suggest that larger patent portfolios, long‐term partnerships, and short‐term agreements lead to factor market rivalry. Specifically, long‐term research partnerships are associated with lower proclivity and vulnerability to attack, while short‐term licensing and marketing agreements with increased proclivity and vulnerability to attack. Lastly, although nonbiotech companies attack biotech firms, the proclivity of the latter to launch cross‐industry attacks is not significant. We discuss how the results contribute to competitive dynamics research and theory.
