COMPETITION AND CASCADES IN MARKETS: AN AGENT‐BASED MODEL OF ENDOGENOUS MERGERS

We present an agent‐based model of endogenous merger formation in a market with turnover of market participants. We describe the dynamics of the model and identify the conditions under which market competition is sufficiently disrupted to prompt extended periods during which mergers are desirable. We also demonstrate how merger waves can be triggered by industry shocks and firm overconfidence. Copyright © 2012 John Wiley & Sons, Ltd.     

Growth without normal capacity utilization

Within the demand-led approach to growth, the long-period tendencies of quantities cannot be effectively studied through theoretical positions entailing normal utilization of capacity. Whether in the form of constant or of average normal utilization, this assumption contradicts the supposed autonomy of aggregate demand. Analysis of the operation of the adjustment of capacity to demand suggests that potentially offsetting forces make fully adjusted positions irrelevant. As quantities cannot be assumed to gravitate towards such positions, the relations between quantity variables determined on the normal utilization hypothesis provide a poor guide to the analysis of reality.     

Wealth,Capital and the Theory of Distribution: Some Implications for Piketty’s Analysis

Thomas Piketty’s Capital in the Twenty-First Century (2014) has been spectacularly successful. One reason for this is that while it often challenges received views and supports a non-apologetic interpretation of capitalism, at the same time it relies on mainstream economics. This theoretical framework, however, is not always conducive to consistency and interpretative accuracy. This paper points out some of the book’s analytical weaknesses and shows that some empirical evidence, a clearer distinction between wealth and capital, and a different theoretical perspective, could lead to questioning some of the book’s claims. In particular, it argues that the increase in the wealth-to-output ratio (but not the capital-to-output ratio) cannot explain the observed changes in income shares. It also contends that non-mainstream perspectives on income distribution and growth suggest that changes in income distribution are due more to policy and power relations than to the factors Piketty identifies.     

The wage–employment relationship in Modigliani's 1944 article

Modigliani's 1944 “Econometrica” article is considered one of the most important efforts to reconcile Keynes with classical economic thinking through the wage rigidity hypothesis. The paper reconstructs the genesis of Modigliani's article and compares Modigliani's and Patinkin's interpretation of the wage–employment relationship. It also discusses Modigliani's contribution to the neoclassical synthesis, arguing that Modigliani's attention to the monetary origin of and solution to unemployment contrasts with the neoclassical synthesis neglecting of the monetary side of the system and its inclination towards fiscal policy.     

Urban sustainability and knowledge: Theoretical heterogeneity and the need of a transdisciplinary framework. A tale of four towns

The academic debate on «sustainable city» is like a large arena, where heterogeneous approaches and contributions, coming from different disciplines, flow into without converging on a common vision. The growing awareness that an increasing percentage of the world's population now lives in urban areas makes the organization of this space a crucial issue for global sustainable development. In order to acquire this challenge, urban studies need to overcome conceptual oppositions, seeking new integrated responses to implement the principle of sustainability at urban scale. This effort requires a new managerial approach of science and policy, which can be based on a transdisciplinary vision to knowledge production. The paper is divided into four different sections. The first and second sections review the theoretical literature on urban sustainability and explore the conceptual relations between knowledge and knowledge production in urban governance processes. The third section presents a comparative empirical analysis based on a survey of 2213 questionnaires carried out in four different urban contexts. The fourth and last section outlines the conclusion, suggesting a new approach to manage knowledge in urban governance, in a trans-disciplinary perspective.     

Rationally inattentive macroeconomic wedges

This paper argues that the solution to a dynamic optimization problem of consumption and labor under finite information-processing capacity can simultaneously explain the intertemporal and intratemporal labor wedges. It presents a partial equilibrium model where a representative risk adverse consumer chooses information about wealth with limited attention. The paper compares ex-post realizations of models with finite and infinite capacity. The model produces macroeconomic wedges and measures of elasticity consistent with the literature. These findings suggest that aconsumption-labor model with information-processing constraints can explain the difference between predicted and observed consumption and employment behavior.     

International strategy and performance—Clustering strategic types of SMEs

This paper identifies different strategic types of internationalised SMEs, in so doing providing managers and entrepreneurs with a much better understanding of the main strategic options and their relationship with the international performance of firms. We provide a theoretical analysis of strategic orientations and strategic behaviour in international SMEs, followed by an empirical investigation based on a sample of Italian SMEs. The SMEs are grouped into strategic types using cluster analysis, and the link between strategic type and international performance is subsequently analysed using logistic regression. The empirical data suggest that there are four broad strategic types, namely an entrepreneurial/growth-oriented group of firms, a customer-oriented group, a product/inward-oriented cluster, and a further group of firms that lacks strategic orientation. The characteristics of the strategic clusters are discussed, and the regression results show that a clear and proactive strategic orientation and its consistency with business strategy leads to improved international performance. This confirms the positive and highly significant role of strategic types.     

On Combining Partial and Incompatible Information in E-negotiation and E-arbitration

The complexity of the problems to be addressed in an e-democracy framework and the variety of involved stakeholders, with different backgrounds, views and access to information sources, lead us to consider the case in which an e-negotiation should be performed among subjects who have partial, sometimes incompatible, information and can hardly gather to discuss issues together, under the supervision of a facilitator. We propose a statistical method which addresses the issue of partial and incompatible information, merging it and then using it to get a final decision, possibly in an automatic way, through processes of e-negotiation and e-arbitration.
