Input/output ranges and performance: an examination of US machine tool producers

Despite the establishment of high-tech multinational enterprises (MNEs) in Ireland since the late 1950s, the country did not succeed in closing the technological gap with most of its EU counterparts. The weak National System of Innovation (NSI), and in particular low business and government R&D levels, combined with a lack of research and technology linkages between MNEs and indigenous firms, explain these poor results. However, the Shannon region in the West of the country presents some specific institutional characteristics that could theoretically make the region a strong technological enclave. The various actors in the region - i.e. the administrative, financial, political and research institutions, as well as the business organizations - have indeed infused a new type of economic development. After a brief review of the available concepts and models articulated around these actors and their interrelationships, the paper analyses whether the Shannon region, taken as an illustrative example, mirrors a specific economic and technological localized setting. The study is based on a survey of indigenous and foreign firms.     

A retrospective on the subprime crisis and its aftermath ten years after Lehman’s collapse

This paper reviews the interactions between policymaking, the financial system and the U.S. economy before, during and after the subprime crisis, with particular attention to current controversies about the policy decisions that led to Lehman’s downfall and their lessons for the future. The first part of the paper documents and analyzes the interactions between policy, financial markets and the economy during the acute and subsequent moderate phases of the crisis as well as during the later gradual exit from the zero lower bound and the extremely slow reduction in high powered money and bank reserves. The remaining parts develop alternative aspects of the thesis that mutual uncertainties inflicted by financial institutions on policymakers and by the latter on financial markets were at the root of the non-negligible surprises that the crisis inflicted on everybody. In particular, it discusses the political economy of bailout operations, reviews and evaluates recent controversies about the reasons for not rescuing Lehman Brothers, and informally presents the structure and policy lessons from a general equilibrium model of the financial sector highlighting the consequences of policy actions that have raised (Knightian) bailout uncertainty. The last section takes a brief look ahead and discusses some longer term consequences of the crisis.

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.
