ENDOGENOUS JOB CONTACT NETWORKS

We develop a model where workers, anticipating the risk of becoming unemployed, invest in connections in order to access information about available jobs that other workers may have. The investment in connections is high when the job separation rate in the labor market is moderate, whereas it is low for either low or high levels of job separation rate. The equilibrium response of network investment to changes in the labor market conditions generates novel empirical predictions. In particular, the probability that a worker finds a new job via his connections increases in the separation rate when the separation rate is low, whereas it decreases when the separation rate is high. These predictions are supported by the empirical patterns that we document for the U.K. labor market.     

Influential listeners: An experiment on persuasion bias in social networks

This paper presents an experimental investigation of persuasion bias, a form of bounded rationality whereby agents communicating through a social network are unable to account for repetitions in the information they receive. We find that, after repeated communication within a social network, social influence depends not only on being listened to by many others, but also on listening to many others. We show that persuasion bias can be viewed as an extreme case of a generalized boundedly rational updating rule in which agents receive more or less attention depending on how many other agents they listen to. The results indicate that behavior in the experiment is consistent with an updating rule according to which agents' social influence is proportional to their indegree.     

The early stages of reform in Polish manufacturingStructural adjustment, ownership and size

This paper argues that a significant adjustment process has taken place in Polish industry in the early stages of the market-oriented reforms. We analyse comprehensive data on two-digit and three-digit manufacturing industries, disaggregated by firm ownership and size. By focusing on a decomposition of labour productivity growth, we obtain results which suggest that structural determinants of the recovery have outweighed cyclical ones. With regard to firm ownership and economic performance, we find that the productive response of state enterprises has been markedly different from that of private firms, with the latter outperforming the former. Finally, our results indicate that size matters, at least among private firms, and our results provide mild evidence of increasing returns.

The tide that does not raise all boats: an assessment of EU preferential trade policies

The aim of this article is to assess the impact of the European Union’s trade preferences on bilateral trade flows. Using highly disaggregated 8-digit import data in a theoretically grounded gravity model framework, we define an explicit measure of preferential tariff margins and use that to estimate sector-specific elasticities. From the methodological point of view, we show that the assessment of these policies’ impacts is very sensitive to the definition of the preferential tariff margin. An important by-product of our procedures is that they can be used to obtain estimates of trade elasticities of substitution, some of the most important parameters in the international trade empirical literature. Results show that actual preferential schemes or possible future policies, such as the transatlantic trade agreement between the USA and the EU (TTIP), have a significant impact on trade volumes, with large differences across sectors.     

Financial stress and sovereign debt composition

Using a panel of 13 advanced economies for the period 1980–2012, we find that periods of impaired financial intermediation mainly accrue to maturity mismatches in sovereign debt. Thus, a higher (lower) share of short-term (medium and long-term) debt leads to an increase in the financial stress index. From a policy perspective, our work suggests that debt management policies translated into longer average maturities of sovereign debt not only reduce the expected debt servicing cost, but also mitigate strains in the financial sector.     

HORIZONTAL MERGERS WITH CAPITAL ADJUSTMENT: WORKERS' COOPERATIVES AND THE MERGER PARADOX

We study the incentives towards horizontal merger among firms when the amount of capital is the strategic variable. We focus on workers' cooperatives, but our conclusions apply also to employment‐constrained profit maximizers. Within a simple oligopoly model, we prove that the horizontal merger, for any merger size, is: (i) privately efficient for insiders as well as for outsiders; (ii) socially efficient if market size is large enough, even in the case of merger to monopoly.     

Conflict of interest and certification in the U.S. IPO market

We examine the long-term return performance of U.S. IPOs underwritten by relationship banks. We show that, over one- to three-year horizons, IPOs managed by relationship banks experience buy-and-hold benchmark-adjusted returns that are similar to those observed for a matching sample of stocks managed by non-relationship underwriters. This result holds even when the returns' skewness and cross-sectional correlation is accounted for. Further, we examine the calendar-time returns on a portfolio that is long the stocks underwritten by relationship banks and short ex-ante similar stocks taken public by non-relationship institutions. Again, we conclude that the two groups of IPOs yield similar long-run returns. These findings support the certification role of relationship banks and suggest that, in this respect, the effect of the 1999 repeal of Sections 20 and 32 of the Glass–Steagall Act has not been negative.     

How to be kind? Outcomes versus intentions as determinants of fairness

We propose a new experimental design to examine the effects of outcomes and intentions on fair behavior. The results indicate that costs matter for the perceived kindness of an action, whereas intentionality does not. In addition, the effects of costs are explained entirely by distributional fairness.     

Market Orientation and R&D Effectiveness in High‐Technology Firms: An Empirical Investigation in the Biotechnology Industry*

There seems to be lack of consensus among informed scholars about the importance a of market orientation for high‐technology firms. This paper gives a comprehensive review of existing empirical studies on the relationship between market orientation and innovation performance and pinpoints two limitations in this research stream that might be at the origin of such controversy. First, extant research often overlooked key innovation outcomes for high‐technology firms, such as those related to research and development (R&D) performance. Second, organizational conditions that can ensure an optimal integration of market knowledge in the innovation process have been less analyzed in the case of these firms. Against this background, the present study contributes to the literature by providing a test of the effect of market orientation on R&D effectiveness and the moderating role of knowledge integration in this relationship, using a sample of Italian biotechnology firms. The study's objectives are addressed in two steps. The first one consists of an in‐depth qualitative study based on semistructured interviews in five biotechnology firms. The second step consists of a follow‐up survey of 50 biotechnology firms. Results from hierarchical multiple regression analysis show that the different dimensions of a market orientation have diverse effects on R&D effectiveness of high‐technology firms: whereas interfunctional coordination has a positive main effect, the effect of customer orientation is moderated by knowledge integration, and competitor orientation has no effect on R&D effectiveness. Post hoc analyses also show two additional results involving a broader set of dependent variables. First, R&D effectiveness mediates the effects of customer orientation and interfunctional coordination on organizational performance. Second, market orientation does not appear to significantly affect R&D efficiency. The present study contributes to current literature in two main respects. First, it adds to previous work on market orientation and innovation by proposing a new dependent variable—R&D effectiveness—which offers a better perspective to understand the impact of market orientation on innovation performance in high‐technology contexts. Second, while part of the current debate on the role of market orientation in high‐tech markets seems to be polarized by positions that sustain its potential drawbacks or, on the contrary, its advantages, this study's findings on the moderating role of knowledge integration shed light on important contingency factors, such as organizational capabilities. The authors discuss the study's limitations and provide directions for future research.     

Midstream value creation in social marketing

ABSTRACT

The purpose of this study is to develop improved understanding of how value is created at the midstream (meso) level in a collaborative smoke-free homes and cars social marketing programme. The study adopts a qualitative approach including interviews and observation. The findings show that the co-creative organisational model adopted for the Smokefree programme affords access to resources and capabilities of midstream actors and provides opportunities for reshaping and mobilising existing value networks. The focal organisation has a key role in coordinating, connecting actors and providing resources to facilitate value co-creation at the network level. The study illustrates that the service interaction allowed for customer-centred cues for action which took into account their context and the existence/lack of resources for value creation. The implications of this study are discussed, in particular, in terms of the role of focal organisations in managing value networks, the social context, configurational fit and resources of actors involved in community-based social marketing and the need for policies and practices to provide health professionals with role support for health promotion.
