Climate for conflict management,exposure to workplace bullying and work engagement: a moderated mediation analysis

The present study investigates a potential preventive factor in relation to workplace bullying. Specifically, we examine how climate for conflict management (CCM) may be related to less bullying, increased work engagement, as well as whether CCM is a moderator in the bullying engagement relationship. The study was based on a cross-sectional survey among employees in a transport company (N = 312). Hypotheses were tested simultaneously in a moderated mediation analysis which showed that bullying and job engagement were related (H1), CCM was related to less reports of bullying (H2), CCM was related to work engagement (H3) and that CCM was indirectly related to job engagement through bullying (H4), but only when CCM was weak (H5). That is, CCM moderated the relationship between bullying and work engagement in that this relationship only existed when CCM was low. The present study contributes to theory within this research field by showing that organizational measures may not only prevent bullying, but may also affect how employees react when subjected to bullying. Furthermore, the effect of climate in relation to bullying may be down to the narrow bandwidth facet of CCM. The study informs employers how they may act to prevent bullying while also reducing the potential negative outcomes of those cases of bullying that inevitably will show up from time to time.     

SHIFTING BOUNDARIES IN ECONOMICS: THE INSTITUTIONAL COGNITIVE STRAND AND THE FUTURE OF INSTITUTIONAL ECONOMICS

This paper aims at contributing to the debate on the future of institutional economics and of the field as a whole by starting from the literature that discusses the relationship between Old‐Original Institutional Economics and New Institutional Economics. It suggests that the process of reunifying OIE and NIE (and evolutionary economics) prompted by part of the literature could be improved by the contribution of the Cognitive Institutional Economics. The paper follows a two‐stage pathway: first, it frames the debate on the relationships between NIE and the OIE and it concentrates on a subset of the literature that shows that NIE's recent developments complicate the distinction between NIE and OIE, and it explores the possibility that NIE and OIE may merge so that an amalgam of NIE, OIE and Evolutionary Economics becomes the next economic paradigm. Secondly, the paper argues that a step forward in the direction outlined by the literature has been made by CIE, which is a research stream that developed from cross‐fertilization among NIE, OIE and the Hayekian contributions to the analysis of institutions. In the concluding remarks, the possible emergence of a single institutional paradigm is discussed in the light of the literature about change in economics.     

Understanding the determinants of information technology adoption: evidence from Italian manufacturing firms

Our empirical study aims at identifying the determinants of Information Technology (IT) adoption by small and medium sized Italian manufacturing firms. An ordered probit analysis is conducted on a sample of about 17?000 firms surveyed by the Italian Statistical Institute, using as a dependent variable an index of IT adoption. Our results show that firm size, geographical location, functional composition of the workforce, R&;D activity, subcontracting, exports and collaboration between firms are all highly significant determinants of IT adoption. Such results are consistent with most of the predictions advanced in the few studies existing on this topic.     

What money buys: clients of street sex workers in the US

The article presents a review of current theoretical and empirical approaches to sex work, followed by the presentation of an original theoretical framework (Della Giusta et al., 2006), which is tested with an econometric model of the characteristics of demand for sex services by a sample of clients of street sex workers in the US. We present findings in relation to stigma and the relationship between paid and unpaid sex that corroborate our model's hypotheses and are in line with findings from other empirical studies. Furthermore, we identify in our sample two diametrically opposite profiles: one for clients whom we label ‘experimenters’, and one for more experienced ones that we name ‘regulars’, we also estimate attitudes toward risk, and draw implications in terms of both policy and future theoretical and empirical research.     

Dynamically stable preferences

In the framework of dynamic choice under uncertainty, we define dynamic stability as a combination of two assumptions prevalent in the literature: dynamic consistency and the requirement that updated preferences have the same “structure” as ex ante ones. Dynamic stability also turns out to be a defining characteristic of the multiplier preferences of Hansen and Sargent (2001) [24] within the scope of variational preferences. Generally, for any class of invariant preferences, dynamic stability is shown to be connected to another independent property — consequentialism.     

House Prices and Stock Prices: Different Roles in the US Monetary Transmission Mechanism*

We analyze the role of house prices and stock prices in the monetary‐policy transmission mechanism in the US, using a structural vector autoregressive model. If we allow the interest rate and asset prices to react simultaneously to news, we find different roles for house prices and stock prices in the monetary transmission mechanism. Following a contractionary monetary‐policy shock, stock prices fall immediately, while the response in house prices is more gradual. Regarding the systematic response in monetary policy, stock prices play a more important role than house prices. As a consequence, house prices contribute more than stock prices to fluctuations in gross domestic product and inflation.     

Hayek and Keynes: From a common critique of economic method to different theories of expectations

The methodological positions of Hayek and Keynes contain striking similarities. Both authors opposed empiricist approaches to economics that assign priority to mere observation as the source of knowledge. Both emphasised intentionality, motivation and human agency. Notwithstanding this common ground, they had different conceptions of how beliefs are formed and had different explanations of thought and action in economics. Hayek grounded his explanation on an evolutionary theory of the mind, i.e. on psychological premises, whereas Keynes based his view of belief formation on probable reasoning, where probability is a logical concept. Starting from psychological premises Hayek maintained that individuals act rationally only by following rules. As a consequence, he considered conventional expectations to be the primary guide for agents in economic life. Keynes agreed that conventional expectations actually guide economic behaviour, but he maintained that they are justified only in situations of total ignorance. In conditions of limited knowledge, agents can base their action on reasonable expectations, independently of conventions. Moreover, agents?particularly those institutions responsible for economic policy?ought to shun conventional behaviour in order to counteract its negative social consequences. We argue that Keynes's theory of expectations is well grounded upon his theory of logical probability. Hence his advocacy of discretionary policy is rationally justified.     

The impact from changes in stock market valuations on investment: new economy versus old economy

This paper investigates whether there is a different impact from changes in ‘new’ and ‘old’ economy stock valuations on private investment for seven OECD economies. A vector autoregressive model is estimated for each individual country, using quarterly data over the period 1990–2000. It is found that the impact from changes in valuations of new economy stocks to investment is roughly the same in North America and in the United Kingdom as in continental Europe. By contrast, the impact from changes in old economy stock valuations on investment is, in general, larger in North America and in the United Kingdom than in continental Europe. Finally, the results suggest that in continental Europe the impact on investment from changes in the valuation of new economy stocks is bigger than for old economy stocks, whereas for North America and the United Kingdom, the impact is more similar.     

A stable demand for money despite financial crisis: the case of Venezuela

The demand for broad money in Venezuela is investigated over a period of financial crisis and substantial exchange rate fluctuations. The analysis shows that there exist a long-run relationship between real money, real income, inflation, the exchange rate and an interest rate differential, that remains stable over major policy changes and large shocks. The long-run properties emphasize that both inflation and exchange rate depreciations have negative effects on real money demand, whereas a higher interest rate differential has positive effects. The long-run relationship is finally embedded in a dynamic equilibrium correction model with constant parameters. These results have implications for a policy-maker. In particular, they emphasize that with a high degree of currency substitution in Venezuela, monetary aggregates will be very sensitive to changes in the economic environment.     

Cost structure and capacity in the Norwegian pelagic fisheries

The parameters of the short-run cost function are estimated for three vessel types taking part in the Norwegian pelagic fisheries: purse seine vessels, trawlers, and coastal vessels. The generalized translog functional form is used. Estimates of returns to scale are calculated and the results indicate that there are substantial economies of scale in all vessel classes. It is further investigated whether excess capacity varies with vessel size and age. The analysis suggests increased quotas per vessel to avoid rent dissipation. With the total allowable catch given, the number of participating vessels must be reduced.
