Pressure and the ability to randomize decision-making: The case of the pickoff play in Major League Baseball

In mixed strategy games, the ability to randomize decisions is a critical strategic necessity, yet studies show that such rational behavior is sometimes elusive. This paper examines mixed strategy play in a natural setting, by looking at a pitcher’s decision to throw the ball to home plate or to throw it to first base in a pickoff play. In the absence of significant pressure, we find that pitchers can effectively randomize their sequence of choices to remain unpredictable, as mixed strategy Nash equilibriums require. However, in the face of pressure, some pitchers are less able to randomize their choices. Our paper is the first empirical study in the English language literature to find that decision makers are unable to randomize their strategic decisions when they face an increased cognitive load due to pressure.

     

Free Trade versus Autarky under Asymmetric Cournot Oligopoly

The paper compares free trade with autarky in an asymmetric multi‐country world under Cournot competition with constant returns to scale and linear demand. We derive respective conditions under which free trade will hurt a country's consumers, benefit its firms, induce it to export, increase its output and raise its welfare. We show that these conditions are linked in a clear order, with one implying the next. We further demonstrate that free trade can reduce world total output and total consumer surplus as well as world welfare. Along the way, we correct several oversights in the literature.     

Change by Design

Over the course of a century of professional practice, designers have mastered a set of skills that can be productively applied to a wider range of problems than has commonly been supposed. These include complex social problems, issues of organizational management, and strategic innovation. Conversely, non‐designers—those in leadership positions in companies, governmental and non‐governmental organizations, professionals in a broad range of services and industries—can benefit from learning how to think like designers. We offer some large‐scale and more finely grained ideas about how this might happen.     

Conflict Evolution: Tracking the Middle East Conflict with Drama Theory

The situation in the Middle East has developed through an episodic process in which the protagonists have periodically changed the ‘game’ that they are playing by inventing new options, seeking to eliminate the options available to others, or by raising or eliminating doubts in the minds of others about their intentions. Such conflict evolution is readily captured by the framework of drama theory which goes some way to explaining the pressures motivating such actions. This paper traces the recent development of relations between the Israelis and the Palestinians through a succession of drama theoretic models. The importance of taking note of interactions at several levels is highlighted: stalemate at one level may be dislodged by actions taken in others. It is concluded that any resolution of the confrontations in the Middle East is likely to require the active involvement of the international community but may be destabilised by pressure from internal factions within the key parties.     

Party Discipline and Environmental Policy: The Role of “Smoke‐filled Back Rooms”*

We adopt the view that greater party discipline induces legislators to commit to promised policies after being elected. We then develop the hypothesis that the effect of party discipline on the stringency of environmental policy is conditional on the degree of government corruption. Our empirical work suggests that greater party discipline results in more stringent environmental policies when the level of corruption is relatively low, but in weaker policies when the level of corruption is comparatively high.     

How universal health care would influence decisions about work and retirement

The current U.S. health care system distorts individual decisions about work and retirement. After a brief explanation of how the current health care system works, this article reviews those distortions and considers how individuals would respond to the implementation of a universal health care system. The author argues that the likely adverse impacts of an employer health insurance mandate on low-skilled workers could be more than offset by a well-designed system of government subsidies.     

Consumer coping strategies: a study of consumers committed to eating local

This paper deals with consumer coping strategies when consumers experience difficulties in implementing an innovation. The particular setting for exploring this issue is a group of consumers in Michigan who are committed to eating local. The paper explores how these consumers cope or balance their commitment to eating local with the constraints they face on buying and preparing local food Following a literature review of coping strategy and consumer coping strategies in relation to innovations, the paper presents the results of three focus groups conducted with members of a Student Organic Farm, a food cooperative and a Slow Food Convivium. The consumers we interviewed mostly adopt problem‐centred, confrontative strategies: they change their food‐consumption habits including shopping, purchasing, cooking, storing and obviously, eating. None of these changes are easy to implement, and most require re‐allocations of time as well as trade‐offs to overcome time and cost barriers. In return, some of these consumers feel empowered. This study allows us to offer a working hypothesis that the process is dynamic: the more committed consumers are, the more they adopt problem‐centred, confrontative strategies and forget more fatalist emotion‐centred or avoidance strategies. These findings contribute to literature on consumers' coping strategies and suggest future research avenues.     

Access to credit and informality among micro and small enterprises in Ethiopia

This paper examines the determinants of Micro and Small and Enterprises (MSEs) access to credit in Ethiopia using detailed firm‐level data collected in 2003. Its basic purpose is to identify the various attributes of a firm that determine its access to credit with an emphasis on the role of firm formality. We find that informal firms are more credit constrained compared to formal firms. A firm’s location, membership of a business association and maintaining an accounting record are found to be important determinants of access to credit. Further, we find firms whose owners have vocational training are more credit constrained than those who are not, as are firms that are exclusively male owned. There is no systematic relation between access to credit and a firm’s age, size and the sector in which it operates. The paper concludes with possible policy interventions designed to improve access to credit for MSEs in Ethiopia.
