Unravelling vs Unravelling: A Memo on Competitive Equilibriums and Trade in Insurance Markets

Both Akerlof (1970) and Rothschild and Stiglitz (1976) show that insurance markets may “unravel”. This memo clarifies the distinction between these two notions of unravelling in the context of a binary loss model of insurance. I show that the two concepts are mutually exclusive occurrences. Moreover, I provide a regularity condition under which the two concepts are exhaustive of the set of possible occurrences in the model. Akerlof unravelling characterises when there are no gains to trade; Rothschild and Stiglitz unravelling shows that the standard notion of competition (pure strategy Nash equilibrium) is inadequate to describe the workings of insurance markets when there are gains to trade.     

How does your kindergarten classroom affect your earnings? Evidence from Project Star

In Project STAR, 11,571 students in Tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade. This article evaluates the long-term impacts of STAR by linking the experimental data to administrative records. We first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27, college attendance, home ownership, and retirement savings. We then document four sets of experimental impacts. First, students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes. Class size does not have a significant effect on earnings at age 27, but this effect is imprecisely estimated. Second, students who had a more experienced teacher in kindergarten have higher earnings. Third, an analysis of variance reveals significant classroom effects on earnings. Students who were randomly assigned to higher quality classrooms in grades K–3—as measured by classmates' end-of-class test scores—have higher earnings, college attendance rates, and other outcomes. Finally, the effects of class quality fade out on test scores in later grades, but gains in noncognitive measures persist.     

Entrepreneurial orientation,market orientation,network ties,and performance: Study of entrepreneurial firms in a developing economy

Entrepreneurial orientation (EO), market orientation (MO) and network ties are typically modeled as separate antecedents of performance. However, the boundary conditions for such models are under-explored, as is their applicability to developing economy settings. Accordingly, drawing on institutional and social capital theories, the current paper argues that the performance benefits of EO and MO are complementary, and vary across different levels of social and business network ties. Using primary data gathered from entrepreneurial firms operating in Ghana, the study findings indicate that aligning high levels of EO and MO improves business performance, and particularly so when social and business network ties are well developed, since under these latter conditions, the performance benefits of aligning EO and MO are greatest.     

Antecedents of mentoring: Do multi-faceted job satisfaction and affective organizational commitment matter?

This study examines the relationships between work attitudes, willingness to mentor and business-to-business salesperson mentoring support. Results provide evidence that individual directed organizational citizenship behavior (altruism) and willingness to mentor may not share as many antecedents as the literature conceptualizes. Willingness to mentor is a strong predictor of serving as a mentor and mentors most willing to mentor provide protégés with the greatest vocational, psychosocial and role modeling support. The findings raise concerns regarding the applicability of organizational citizenship behavior theory as a framework for understanding why employees mentor.     

When birds flock together: an identification of the destination social servicescape

ABSTRACT

While servicescapes have been studied in a variety of travel and tourism domains, the phenomenon has been largely ignored at the destination level. This is especially true when it comes to considerations of the social servicescape, which is reflective of the extent to which the mere presence of other destination visitors can influence affective responses to the destination experience. Accordingly, the purpose of this research is to propose and empirically test a model of the destination social servicescape that explores perceived psychographic similarity within the social servicescape and the effects of this construct on affective evaluations and behavior.     

Praxeology,Experimental Economics and the Process of Choice: F.A. Hayek and Vernon Smith on the Misesian Action Axiom

Mises’s action axiom postulates that human action is purposeful behavior. While this axiom is the building block for a powerful methodology, it is also incomplete, because it sets aside the underlying processes of decision-making. And while Mises does not dismiss the gap between intention and action, he is silent on it, relegating such a study to psychology. We contend that a study of underlying thought patterns and the process of choice – rather than contradicting praxeology and the action axiom – in fact complements the writings of Mises. To demonstrate this, we look at two authors: F.A. Hayek and Vernon Smith. Hayek’s theory of the sensory order sheds light on the process of choice, and explains how decision-making is contextually embedded. Smith’s concepts of ecological rationality and neurological “hard-wiring” help us understand decision-making. We argue that cognitive foundations enrich our understanding of the process of choice, and thus of the Misesian action axiom.     

The Form of Relationship between Firm‐Level Product Innovativeness and New Product Performance in Developed and Emerging Markets

This study compares the new product performance outcomes of firm‐level product innovativeness across a developed and emerging market context. In so doing, a model is constructed in which the relationship between firm‐level product innovativeness and new product performance is anticipated to be curvilinear, and in which the nature of this relationship is argued to be dependent on organizational and environmental factors. The model is tested using primary data obtained from chief executive officers and finance managers in 319 firms operating in the United Kingdom, an advanced Western market, and 221 firms from Ghana, an emerging Sub‐Saharan African market. The model is assessed using a structural equation model multigroup analysis approach with LISREL 8.5. In the United Kingdom and Ghana, the basic form of the relationship between firm‐level product innovativeness and business success is inverted U‐shaped, but the strength and/or form of this relationship changes under differing levels of market orientation, access to financial resources, and environmental dynamism. While commonalities are identified across the two countries (market orientation helps firms leverage their product innovativeness), differences are also observed across the samples. In Ghana, access to financial resources enhances the relationship between product innovativeness and new product performance, unlike in the United Kingdom where no moderation is observed. Furthermore, while U.K. firms leverage product innovativeness to their advantage in more dynamic environments, Ghanaian firms do not benefit in this way: here, high levels of innovation activity are less useful when markets are more dynamic. If the study's findings generalize, there are a number of implications for managers of both emerging and developed market businesses. First, managers in both developed and developing market firms should focus on determining and managing an optimal balance of novel and intensive product innovativeness within the context of their unique institutional environments. Second, for emerging market firms, a market orientation capability helps businesses leverage local market intelligence, enabling them to compete with multinational giants flocking to emerging markets, but typical developed market learning approaches may be insufficient for multinational firms when seeking to compete in emerging markets. Third, for emerging market firms, access to finances helps deliver product innovation success (although this is not the case for developed market firms, possibly due to strong financial institutions). Finally, unlike developed market firms, burdened by institutional voids at home, emerging market firms appear to be less capable of competing on an innovation front in more dynamic market conditions. Accordingly, policymakers in emerging markets should consider identifying ways to help businesses raise market orientation levels, and seek to create conditions that enhance access to financial capital (e.g., direct financing, matching grants, tax rebates, or rewarding firms that innovate creatively and intensely). Likewise, since environmental dynamism is likely to be a growing issue for emerging markets, efforts to help firms become more adept at keeping up with more agile developed market counterparts are needed.     

Does organizational creativity always drive market performance?

This study develops and tests arguments that the relationship between organizational creativity and market performance is channeled through new product development (NPD) capability, and that the indirect effect of creativity on performance, via NPD capability, is conditional upon levels of environment dynamism and market responsiveness. The proposed relationships are tested on a sample of 221 small‐ and medium‐sized enterprises (SMEs) in a major sub‐Saharan African market. Findings from the study indicate that process and product NPD capabilities partially mediate the effect of novelty and usefulness elements of organizational creativity on market performance. The study further finds that while environment dynamism weakens the indirect effects of novelty and usefulness of organizational creativity, via process and product NPD capabilities, on market performance, the effects are strengthened under conditions of greater responsiveness to target market needs. A theoretical contribution from this study is the finding that how organizational creativity dimensions drive market performance is more complex than previously thought: it depends on whether or not organizational creativity components are first used to develop an organization's process and product innovation capabilities, and whether target market environment conditions are dynamic and an organization has ability to respond to target market demands.     

Examining the Impact of Restaurant Innovativeness on Relationship Quality in Luxury Restaurants

ABSTRACT

Despite the importance of innovation as a determinant for the success of restaurant businesses, little research has been conducted on the postconsumption evaluations of the image of restaurant innovativeness as perceived by the customer. In order to fill this important gap in the literature, the purpose of this study is to examine the perception of restaurant innovativeness and the effect of this construct on relationship quality. Based on a review of the literature, a conceptual model was developed hypothesizing the effects of the overall image of restaurant innovation on three determinant attributes of relationship quality: trust, commitment, and satisfaction. The model was then tested using data collected from 398 luxury restaurant patrons. The results of data indicate that the overall image of restaurant innovativeness is positively related to relationship quality in the luxury restaurant setting. The theoretical and practical implications of these results are considered.     

‘Stochastically more risk averse:’ A contextual theory of stochastic discrete choice under risk

Microeconometric treatments of discrete choice under risk are typically homoscedastic latent variable models. Specifically, choice probabilities are given by preference functional differences (given by expected utility, rank-dependent utility, etc.) embedded in cumulative distribution functions. This approach has a problem: Estimated utility function parameters meant to represent agents’ degree of risk aversion in the sense of Pratt (1964) do not imply a suggested “stochastically more risk averse” relation within such models. A new heteroscedastic model called “contextual utility” remedies this, and estimates in one data set suggest it explains (and especially predicts) as well as or better than other stochastic models.
