企业家们的新年祝福

商场在疯狂甩卖,其降幅和冷清堪比非典时期;出租车的空位多了,地铁公交却更拥挤了;公司的年终奖打折了,企业都在喊亏损;华尔街爆发危机了,全球的股市都在跌;公司晚会不办了,出国旅游取消了,皮草名车也不买了……经济危机真的来了。企业家们受影响了么?显然不会例外。央行行长的头发都白了,而更多企业家的头发都掉光了;有的企业家绝处逢生,东山再起,而有的从云端落下,光环尽失;有的企业家卷款逃

Analysis of high dimensional multivariate stochastic volatility models

This paper is concerned with the Bayesian estimation and comparison of flexible, high dimensional multivariate time series models with time varying correlations. The model proposed and considered here combines features of the classical factor model with that of the heavy tailed univariate stochastic volatility model. A unified analysis of the model, and its special cases, is developed that encompasses estimation, filtering and model choice. The centerpieces of the estimation algorithm (which relies on MCMC methods) are: (1) a reduced blocking scheme for sampling the free elements of the loading matrix and the factors and (2) a special method for sampling the parameters of the univariate SV process. The resulting algorithm is scalable in terms of series and factors and simulation-efficient. Methods for estimating the log-likelihood function and the filtered values of the time-varying volatilities and correlations are also provided. The performance and effectiveness of the inferential methods are extensively tested using simulated data where models up to 50 dimensions and 688 parameters are fit and studied. The performance of our model, in relation to various multivariate GARCH models, is also evaluated using a real data set of weekly returns on a set of 10 international stock indices. We consider the performance along two dimensions: the ability to correctly estimate the conditional covariance matrix of future returns and the unconditional and conditional coverage of the 5% and 1% value-at-risk (VaR) measures of four pre-defined portfolios.     

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.

Bourdieu Comes to Town: Pertinence,Principles, Applications

This article frames the themes of the two‐part Interventions section ‘Bourdieu Comes to Town’. I first establish the pertinence of Bourdieu's sociology for students of the city by revisiting his youthful work on power, space, and the diffusion of urban forms in provincial Béarn and colonial Algeria. In both cases, urbanization is the key vector of transformation, and the city, town, or camp the site anchoring the forces dissolving the social fabric of the French countryside and overturning French imperialism in North Africa. These early studies establish that all social and mental structures have spatial correlates and conditions of possibility; that social distance and power relations are both expressed in and reinforced by spatial distance; and that propinquity to the center of accumulation of capital (economic, military, or cultural) is a key determinant of the force and velocity of social change. Next, I discuss four principles that undergird Bourdieu's investigations and can profitably drive urban inquiry: the Bachelardian moment of epistemological rupture, the Weberian invitation to historicize the agent (habitus), the world (social space) and the categories of the analyst (epistemic reflexivity); the Leibnizian‐Durkheimian imperative to deploy the topological mode of reasoning; and Cassirer's command to heed the constitutive efficacy of symbolic structures. The plasticity and productivity of his concepts suggest that Bourdieu can not only energize urban inquiry but also merge it into a broader analytic of the trialectic of symbolic division, social space, and the built environment. This paves a pathway for reconceptualizing the urban as the domain of accumulation, differentiation and contestation of manifold forms of capital, which makes the city a central ground, product, and prize of historical struggles.

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.
