Evaluating the performance of the search and matching model

Does the search and matching model fit aggregate U.S. labor market data? While the model has become an important tool of macroeconomic analysis, recent literature pointed to some significant failures in accounting for the data. This paper aims to answer two questions: (i) Does the model fit the data, and, if so, on what dimensions? (ii) Does the data “fit” the model, i.e. what are the data which are relevant to be explained by the model?The analysis shows that the model fits certain specifications of the data on many dimensions, though not on all. This includes capturing the high persistence and high volatility of most of the key variables, the negative co-variation of unemployment and vacancies, and the behavior of the worker job finding rate. A key role in this fit is played by the convexity of hiring costs and the stochastic properties of the separation rate. The latter is a major component of the rate discounting the future value of the job-worker match.The paper offers a workable, empirically grounded version of the model for the analysis of aggregate U.S. labor market dynamics.     

Liquidity traps, learning and stagnation

We examine global economic dynamics under learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is locally but not globally stable. Large pessimistic shocks to expectations can lead to deflationary spirals with falling prices and falling output. To avoid this outcome we recommend augmenting normal policies with aggressive monetary and fiscal policy that guarantee a lower bound on inflation. In contrast, policies geared toward ensuring an output lower bound are insufficient for avoiding deflationary spirals.     

Eating with EatWith: analysing tourism-sharing economy consumers

In recent years, a growing body of research has analysed tourism-sharing economy users. While several studies have revealed the specific motivations of tourists for participating in such activities, there is an apparent lacuna with regard to understanding the generic motivations of such consumers. In response to this literature gap, the current study explores the motivations of these users, aiming to shed light on their values, lifestyles and consumption preferences. The motivations of sharing economy users were examined using a quantitative survey involving 738 consumers of EatWith – a global sharing economy marketplace that offers a communal dining experience. The study's findings indicate that EatWith users have the generic primary motivation of achievement. The findings present several contributions to scholars and practitioners, and propose that sharing economy users are affected both by the specific motivations of social considerations, environmental considerations and economic considerations, and by their primary motivations of ideals, achievement and self-expression.     

The ordinal Nash social welfare function

A social welfare function entitled ‘ordinal Nash’ is proposed. It is based on risk preferences and assumes a common, worst social state (origin) for all individuals. The crucial axiom in the characterization of the function is a weak version of independence of irrelevant alternatives. This axiom considers relative risk positions with respect to the origin. Thus, the resulting social preference takes into account non-expected utility risk preference intensity by directly comparing certainty equivalent probabilities. The function provides an interpretation of the Nash-utility-product preference aggregation rule. Necessary and sufficient conditions for the function to produce complete and transitive binary relations are characterized.     

Advancing Ethics in Public Organizations: The Impact of an Ethics Program on Employees’ Perceptions and Behaviors in a Regional Council

Ethics in public administration has been a subject of growing interest for both researchers and practitioners interested in the future of governance. This study examined the relationship between ethics and performance in local governance. We tested the effects over time of an ethics program on employees’ perceptions (awareness of the code of ethics, ethical leadership, inclusion of employees in ethical decision making [EDM], ethical climate [EC], organizational commitment, and quality of work life [QWL]) and behavior (organizational citizenship behavior) in one Israeli regional council. We conducted a longitudinal study of 108 employees, using data from a two-phase survey (before implementation of the ethics program and a year after) and objective assessments of employees’ behavior through managers’ evaluations. The main findings show that the ethics program was very effective, resulting in greater awareness of the code of ethics, increased inclusion of employees in EDM, and an improved EC. Furthermore, ethical leadership was positively related to employees’ awareness of the code of ethics, increased inclusion of employees in EDM, an improvement in the EC, greater organizational commitment, and higher QWL. Implications and suggestions for future studies are discussed.     

Data-based negotiator allocation management

Negotiation abilities are difficult to assess, and negotiation outcomes are difficult to predict. This leads to possible deficiencies in resource allocation for negotiation tasks. In this article, we discuss the merits of a data-based approach for the allocation of negotiators to negotiation tasks. We provide a framework for negotiation allocation management that includes a method for assessing negotiator strength. The negotiator strength measure compares observable negotiation outcomes relative to similar outcomes in similar situations. We provide examples for using our framework and show evidence for its appeal when using industry data. We discuss implications for managers and provide key takeaways.     

Destination marketing during and following crises: combating negative images in Asia

The goal of this study is to analyze which strategies Asian officials and marketers have adopted in order to combat stereotypes, negative perceptions, and crises in order to repair destination images and bring back visitors. The study includes qualitative content analyses of news reports, press interviews, and campaigns in order to uncover media policy, strategies, events, and marketing initiatives used since 2008. The conceptual framework used was the “multi-step model for altering place image”, which offers three types of strategies to use in order to repair a destination’s negative image during and after a crisis: source, message, and audience.
