In search of an evolutionary edge: trading with a few, more, or many

Consider a population of farmers who live around a lake. Each farmer engages in trade with his m adjacent neighbors, where m is termed the “span of interaction.” Trade is governed by a prisoner’s dilemma “rule of engagement.” A farmer’s payoff is the sum of the payoffs from the m prisoner’s dilemma games played with his ^m/₂^m/_2 neighbors to the left, and with his ^m/₂^m/_2 neighbors to the right. When a farmer dies, his son takes over. The son who adheres to his father’s span of interaction decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous member of the group comprising his father and his father’s m trading partners. Under a conventional structure of payoffs, it is shown that a large span of interaction is detrimental to the long-run coexistence of cooperation and defection, and conditions are provided under which the social outcome associated with the expansion of trade when individuals trade with a few is better than that when they trade with many. Under the stipulated conditions it is shown, by means of a static comparative analysis of the steady state configurations of the farmer population, that an expansion of the market can be beneficial in one context, detrimental in another.     

Interest Rates Fluctuations and the Advantage of Long-Term Debt Financing: A Note on the Effect of the Tax-Timing Option

When interest rates fluctuate, issuing long-term debt may implicitly generate a valuable tax-timing option. The holder of long-term debt has an optimal-trading taxtiming option to immediately realize capital losses if an increase in interest rates lowers the price of the bond below the original issue price. In contrast, if interest rates decrease and the bond price is greater than the original issue price, the holder would prefer to defer the realization of capital gains. This tax-timing option confers an advantage for issuing long-term debt. Our formal presentation also highlights how the tax-timing options of long-term debt may increase the debt capacity of the firm.

Language and market inclusivity for women entrepreneurship: the case of microfinance

Inclusive markets are key to fostering female entrepreneurship, and the microfinance sector has recognized and acted on this. Existing research has studied how institutions and organizational factors facilitate the process by which microfinance and other financial intermediaries tackle gender-based financial exclusion. But while the role of cultural institutions has been recognized as important, little research has systematically integrated culture in the study of gender-based financial exclusion. We posit that language is a cultural institution that influences the extent to which financial intermediaries are successful in outreaching women and supporting female entrepreneurship. Inspired by a performativity approach, we develop a set of hypotheses that delineate how a specific feature of language, gender marking in grammar, moderates the role of institutional (state capacity) and organizational (NGO status and global ties) factors in shaping microfinance outreach to women. Using the ratio of female to male borrowers in 2361 microfinance organizations from 115 countries during the period 1995–2015, we confirm that market inclusion of women depends on organizational and institutional factors, and that gender marking in grammar influences those relationships.     

easyJet® pricing strategy: Should low-fare airlines offer last-minute deals?

easyJet, one of Europe’s most successful low-cost short-haul airlines, has a simple pricing structure. For a given flight, all prices are quoted one-way, a single price prevails at any point, and, in general, prices are low early on and increase as the departure date approaches. We observe from these policies and from the empirical section of this paper that easyJet employs three distinct strategies: 1) it does not offer last-minute deals, 2) it offers a single class and lets price be the sole variable that controls demand, and 3) it varies the time at which tickets are first offered for sale (duration of sale). The first two policies are in stark contrast to traditional airline pricing strategies. Many airlines offer last-minute deals, either directly or via resellers. Second, the current prevailing practice is to control demand via seat allocation to various classes rather than by offering a single class and letting price be the sole variable that controls demand. The main objective of this research is to study the conditions under which offering a last-minute deal is optimal under the single-price policy. We also learn how the duration of ticket sales is affected by consumer characteristics. We find that, for an intermediate capacity level, uncertainty with respect to the arrival of the business segment will cause the firm to offer last-minute deals and thus partially price-discriminate within the tourist segment. The same is true for uncertainty with respect to the actual behavior of the firm: if consumers are uncertain whether the firm will offer last-minute deals, then, in equilibrium, both in a one-shot game and in a repeated game, the firm will, with some probability, offer such deals. In addition, we found that for an intermediate capacity level, the larger the number of segments (that differ in price sensitivity), the longer the duration of the period in which tickets are offered for sale.

Price discrimination in service industries

This article outlines recent methods and applications directed at understanding the profit and consumer welfare implications of increasingly prevalent price discrimination strategies in the service sector. These industries are typically characterized by heterogeneity in consumers?? valuation and usage of the service, resale constraints, and a focus on price as the service??s key attribute. The article focuses on how firms use nonlinear pricing or bundling strategies to benefit from the heterogeneity in consumer demand. We describe the basic economic model commonly used in the literature to analyze such strategic choices and present recent methodological improvements to this benchmark. A discussion of existing applications and future research opportunities concludes the article.     

On modelling the informal sector

A recent plea by Robert Hackenberg to develop new conceptual models in order ‘to take full account of the new realities of the urban informal sector’ and ‘rid the field from divergent connotations’ is questioned. It seems that existing models easily lend themselves to analysis of the formal-/informal-sector interactions and that divergent conditions necessarily lead to ‘contradictions’. Thus, the existing arsenal of models cannot be held responsible for ‘analysis paralysis’. New research on the informal sector, rather than aiming at ultra-generalizations, should concentrate on issues such as identification of the determining factors of the urban production technologies and the nature of linkages and elasticity of substitution between formal and informal production.     

Do security breaches matter? The shareholder puzzle

This article analyzes the effect of computer breaches on publicly traded equities from 2005 to 2017. An event study is performed and breaches analyzed conditioned on whether the breach announcement has been made in the mainstream media or through other channels. We find that in the period prior to the announcement date in the media, the mean abnormal return is negative, reflecting a likely leakage of information. In the period following the announcement date, the mean abnormal return is positive, often more than offsetting the previous declines. The findings have important implications for analysts, portfolio managers, institutional investors, and regulators.     

A policy response to a downside of the integration of economies: An impossibility theorem

Recent research shows that the merger of economies increases aggregate stress. This paper shows that there is no income distribution policy which will ensure that the wellbeing of the individuals belonging to merging economies does not fall below their pre-merger level.
