Information acquisition,coordination, and fundamentals in a financial crisis

This paper reconciles the two explanations of a financial crisis, the self-fulfilling prophecy and the fundamental causes, in an empirically-relevant framework, by explicitly modeling the costly voluntary acquisition of information about fundamentals in a variant of Diamond and Dybvig [Diamond, D., Dybvig, P., 1983. Bank runs, deposit insurance, and liquidity. Journal of Political Economy 91, 401–419]. The model exhibits strategic complementarity in information acquisition. In the “partial run” equilibrium investors engage in costly evaluation of projects, so that banks with lower-return projects fail. There also exist the classic “full-run” and “no-run” equilibria in which there is no project evaluation. Investors’ coordination on a specific equilibrium is triggered by a self-fulfilling prophecy. So, financial crises are seen as both fundamentals-based and self-fulfilling prophecies-based phenomena.     

Why Have Debt Ratios Increased for Firms in Emerging Markets?

I study trends in capital structure between 1980 and 2004 in a sample of over 11,000 firms from 34 emerging markets. The average firm's market‐value debt ratio rose by 15 percentage points over this quarter century. I study how this rise in leverage was influenced by firm‐level factors and by the availability of debt financing at the country level. The central finding is that the increase in debt ratios can largely be attributed to changes in the characteristics of emerging market firms over this period. For the average firm, the most prominent determinants of capital structure – size, profitability, asset tangibility, and growth opportunities – all shifted in the direction implying a higher optimal level of debt. At the country level, increased financial development within the country is associated with lower debt ratios, but increased financial openness to foreign markets is associated with higher debt ratios.     

Limited participation and consumption-saving puzzles: A simple explanation and the role of insurance

In this paper, we show that the existence of a large, negative wealth shock and insufficient insurance against such a shock could explain both the limited stock market participation puzzle and the low-consumption–high-savings puzzle. We then conduct an empirical analysis on the relation between household portfolio choices and access to private insurance and various types of government safety nets. The empirical results demonstrate that a lack of insurance against large, negative wealth shocks is positively correlated with lower participation rates and higher saving rates. Overall, the evidence suggests an important role of insurance in household investment and savings decisions.     

Leverage regulation: An agent-based simulation

An agent-based financial market model is used to simulate the effects of financial regulation to reduce financial leverage. Results suggest that regulating leverage using margin calls can lead to less frequent financial crises per century, however, it creates harder hit financial crises than without regulation. In addition, regulation where the central authority tries to prick bubbles also leads to less frequent financial crises, but, creates greater volatility. Lastly, I find that leverage regulation where agent’s ability to borrow is not dependent on price produces less frequent crises and less volatility than the other regimes.     

A Cooperative Game Theory of Noncontiguous Allies

This paper develops a cooperative game-theoretic representation of alliances with noncontiguous members that is based on cost savings from reducing overlapping responsibilities and sequestering borders. For various scenarios, three solutions (the Shapley value, nucleolus, and core's centroid) are found and compared. Even though their underlying ethical norm varies, the solutions are often identical for cases involving contiguous allies and for rectangular arrays of noncontiguous allies. When transaction costs and/or alternative spatial configurations are investigated, they may then differ. In all cases the cooperative approach leads to a distribution of alliance costs that need not necessarily coincide with the traditional emphasis on gross domestic product size as a proxy for deterrence value (the exploitation hypothesis). Instead, burdens can now be defined based upon a country's spatial and strategic location within the alliance.     

Ability and specialization among economic researchers

It is not obvious whether a firm's more talented workers should be more specialized, and in fact, the relationship between ability and specialization seems to differ across industries. In this paper, I examine the case of knowledge production in economic research, and find that abler economists tend to publish more general research. This result suggests substitutability between general and specialized skill in research. Copyright © 2008 John Wiley & Sons, Ltd.     

Entrepreneurial processes in social contexts: how are they different, if at all?

Scholars have compared and contrasted commercial and social entrepreneurship along a variety of dimensions, suggesting that entrepreneurial antecedents and outcomes differ within a social context. However, little is known about whether entrepreneurial processes differ within social contexts. In this paper, we ask to what extent the antecedents and outcomes that make social entrepreneurship unique influence entrepreneurial processes. Using an inputs–throughputs–outputs framework, we assess the relationship between four antecedents (social mission/motivation, opportunity identification, access to resources/funding, and multiple stakeholders) and three outcomes (social value creation, sustainable solutions, and satisfying multiple stakeholders) to the dimensions of entrepreneurial orientation (innovativeness, proactiveness, risk-taking, competitive aggressiveness, and autonomy) (Lumpkin and Dess, Acad Manag Rev 21(1):135–172, 1996). Our analysis suggests that many entrepreneurial processes remain essentially the same or are affected only slightly. However, autonomy, competitive aggressiveness, and risk-taking are influenced to some extent by the presence of multiple stakeholders and access to resources/funding. Entrepreneurial processes may also differ when applied to efforts to satisfy multiple stakeholders and achieve sustainable solutions. We subsequently discuss the implications of our analysis for future social entrepreneurship research and practice.     

Funding the story of hybrid ventures: Crowdfunder lending preferences and linguistic hybridity

Prosocial crowdfunding platforms are venues for individual lenders to allocate resources to ventures that specifically pursue economic and social value. In a setting where hybridity is expected, do crowdfunders respond positively to category-spanning ventures, or do they prefer to fund ventures that are more clearly situated within a single category? Drawing on theory rooted in category membership and spanning, our hypotheses test whether prosocial crowdfunding lenders will more quickly allocate resources to hybrid microenterprises that communicate their hybridity, or to those that communicate a single one of their dual aims. Our study demonstrates that even in such a setting, crowdfunders lend more quickly to microenterprises that position themselves within a single linguistic category in which the social is emphasized over the economic. This suggests that how hybrid organizations position themselves in their linguistic narratives has a significant impact on resource allocation by external prosocial audiences.
