WHAT'S TO KNOW ABOUT THE CREDIBILITY OF EMPIRICAL ECONOMICS?

The scientific credibility of economics is itself a scientific question that can be addressed with both theoretical speculations and empirical data. In this review, we examine the major parameters that are expected to affect the credibility of empirical economics: sample size, magnitude of pursued effects, number and pre‐selection of tested relationships, flexibility and lack of standardization in designs, definitions, outcomes and analyses, financial and other interests and prejudices, and the multiplicity and fragmentation of efforts. We summarize and discuss the empirical evidence on the lack of a robust reproducibility culture in economics and business research, the prevalence of potential publication and other selective reporting biases, and other failures and biases in the market of scientific information. Overall, the credibility of the economics literature is likely to be modest or even low.     

The Geography of Innovation in China and India

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.

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.     

SHERLOCK HOLMES AND THE SEARCH FOR TRUTH: A DIAGNOSTIC TALE

Abstract. In four novels and fifty-six short stories, Sir Arthur Conan Doyle developed the characters of Mr. Sherlock Holmes and his trusted friend and chronicler, Dr. John Watson. The creation of the brilliant sleuth and his partner who, although not possessing genius, stimulated it in his friend, was a masterstroke. The adventures, memoirs, return, last bow, and case book of Sherlock Holmes, as well as the four famous novels, are stories of sheer delight. Econometrics may not have the everlasting charm of Holmesian characters and adventures, or even a famous resident of Baker Street, but there is much in his methodological approach to the solving of criminal cases that is of relevance to applied econometric modelling. Holmesian detection may be interpreted as accommodating the relationship between data and theory, modelling procedures, deductions and inferences, analysis of biases, testing of theories, specification and respecification of theories, re-evaluation and reformulation of theories, and finally reaching a solution to the problem at hand. With this in mind, can applied econometricians learn anything from the master of detection? This paper provides an outline of Holmesian deduction through the various stages of accommodation, namely problem solving, theorizing before data, examining the quality of data, the meaning of truth, reconciliation with data, and testing of theories. Testing procedures, especially the use of diagnostics, are the most common research method used in econometrics for examining a number of specifications within a modelling cycle of specification, estimation and evaluation. A diagnostic approach to the evaluation of empirical models is outlined through testing the key assumptions which define the parameter space for purposes of inference.
