Perception of Risks and Preferences for Locally Grown Produce: A Marketing System Approach

In recent years, the “buy local” movement has escalated in popularity. This trend is redefining how value along the food chain is shared between producers, retailers, and consumers. A theoretical model was developed and used to evaluate how consumers formulate preferences for locally grown attributes, with an emphasis on consumers’ perceptions of food safety risk. Linkages between locally grown produce attributes, perceived macro outcomes, and value allocation to consumers are then examined using random utility discrete choice models. While results were mixed depending on frequency of purchasing locally grown produce, they do indicate that consumer preferences are driven by perceived food safety risk and other macro outcomes. For example, consumers who frequently purchase locally grown produce perceive these products to be environmentally friendly and to improve their quality of life.     

NAIRU Estimates for Germany: New Evidence on the Inflation–Unemployment Tradeoff

Meaningful estimates of the non‐accelerating inflation rate of unemployment (NAIRU) within a Phillips curve framework require an identified tradeoff between inflation and unemployment. However, observations of inflation and unemployment are equilibrium points giving rise to a simultaneity problem. We assess conventional identifying assumptions in the literature on the German NAIRU in a general bi‐variate equations system of inflation and unemplyoment. We use a data‐driven method for identification based on shifts in the relative volatility of shocks to unemployment and inflation to identify the tradeoff for Germany. Our results support models which estimate a contemporaneous effect of unemployment on inflation and those which model inflation and unemployment jointly.     

ECONOMIC POLICY UNCERTAINTY EFFECTS ON CREDIT AND STABILITY OF FINANCIAL INSTITUTIONS

We examine policy‐related economic uncertainty effects on the availability of credit, non‐performing loans and loan loss provisions using a panel of 18 countries. We provide significant evidence that uncertainty reduces the availability of credit while leading to increases in banks' non‐performing loans and loan loss provisions, distorting sectoral stability. Our findings are economically meaningful.     

The time‐varying performance of UK analyst recommendation revisions: Do market conditions matter?

This study examines the time‐varying performance of investment strategies following analyst recommendation revisions in the UK stock market, with specific emphasis on the impact of changing market conditions. We find a negative relationship between the recommendation performance and market conditions as measured in terms of past market return and market volatility. In particular, the upgrade (downgrade) portfolio generates significantly positive (negative) net abnormal returns in bad market conditions (e.g., the dot‐com bubble burst in 2000 and the credit crisis in 2007), but not in other periods of time. Moreover, our non‐temporal threshold regression analysis shows that the reported negative relationship disappears when market conditions become better, i.e., when the past market return (market volatility) is higher (lower) than a certain level, indicating the importance of taking non‐linearity into account in the long sample period as examined in this study. Our time‐series bootstrap simulations further confirm that the superior recommendation performance in bad market conditions is not due to random chance; analysts have certain skills in making valuable up/downward revisions in bad markets.

L'innovation dans les services à forte intensité de connaissances (SFIC)†

This article examines the determinants of innovation in knowledge intensive business services (KIBS), generally hypothesizing that differences in the effect of the determinants of innovation depend on the type of innovation developed within KIBS. The study results are based on estimates of two econometric models using data from a survey of 392 firms in the province of Ontario, Canada.     

The financialization of the non‐financial corporation. A critique to the financial turn of accumulation hypothesis

One aspect in which non‐financial corporations (NFCs) are said to be financialized is that they have been increasingly engaged in financial accumulation from which they derive a growing proportion of financial income. This is what we call the financial turn of accumulation hypothesis. In this article, we show that the evidence used to sustain it, in the U.S. setting, has to be reconsidered. Our findings show that, contrary to the financial turn of accumulation hypothesis, financial income averages 2.5% of NFCs’ total income since the 1980s, oscillating since the beginnings of the 1990s until 2005 and then declining. In terms of assets, some of the alleged financial assets might actually reflect other activities in which NFCs have been increasingly engaged, such as tax avoidance, internationalization of production, activities refocusing and M&As.     

Modelling New Zealand dairy products: evidence on export survival and duration

This article presents evidence concerning the pattern of New Zealand dairy exports duration and survival from 1989 to 2017. It also analyses the influence of a set of supply, demand and gravity‐type drivers on the hazard rate for New Zealand dairy export relationships. The findings are summarised as follows. First, New Zealand dairy export relationships are dynamic with numerous entries and exits to and from foreign markets. Around half of the relationships survived for only 1–2 years at the sequence level. Second, duration of sequence, left‐censoring, initial export, decomposed sequences, New Zealand export price index, the number of cows available for dairy production, the number of origins and destinations, and destination partner’s GDP are the most significant factors reducing the hazard rate of export relationships. As regards the effects of the non‐tariff measures, it is interesting that technical barriers of trade are found to significantly decrease the hazard rate. Only pre‐shipment inspection and contingent trade protective measures are significant impediments to New Zealand dairy export relationships. Finally, hazard probabilities for New Zealand dairy export relationships are estimated to be ‘L‐shaped’ over time, whether or not non‐tariff measures are applied to New Zealand dairy products.     

Who's the Boss at the Top? A Micro‐Level Analysis of Director Expertise,Status and Conformity Within Boards

In this paper we address how director expertise impacts a director's social status and conformity within the board. Our results, derived from two unique multi‐source datasets of peer ratings on director status and conformity of non‐executive directors from Dutch organizations, indicate that industry‐specific expertise and financial expertise differently impact directors’ social status and influence within the board. We find that directors’ individual performance orientation – the motivation to demonstrate expertise – acts as an important contingency for expertise to increase directors’ status within the board. Additional analyses using archival data and interviews with non‐executive directors substantiate our findings and provide additional insight into the dynamics operating within boards. This study extends existing research on boards of directors and provides unique micro‐level insights into the boardroom dynamics that connect director expertise to director status and conformity within boards.
