The limited success of behavioural strategies in injury prevention has been attributed to failure to properly apply behaviour change models to intervention design and the explanation of safety behaviours. However, this paper contends that many health behaviour change interventions do not succeed because they fail to take into account the habitual quality of most health and safety-related behaviour; a more complete model of behaviour change needs to be based on a better understanding of the role of habit. The overall aim is to contribute to better understanding of behavioural strategies for injury prevention. When habits are weak, attitudes and intentions predict behaviours, but as behaviours turn into habits, they become better predictors of future behaviour than attitudes or intentions. Furthermore, where habits are strong, individuals are less likely to act on new information, evaluating counter-habitual information negatively. Integrating the concepts of strong and weak habits with upstream and downstream strategies, a framework is presented for tailoring strategies to the habit strength of the target behaviour. 相似文献

The purpose of this study is to identify key institutional determinants of firm emergence and growth. We do this using various types of data from Sweden. A characterization of a number of institutions and policy measures shows that they are likely to have contributed to an environment that discourages entrepreneurial activity and firm growth. Aspects dealt with include: missing arenas for entrepreneurship in the care sectors and for household-related services, taxation of entrepreneurial income, incentives for wealth accumulation, wage-setting institutions and labor market regulations. Using original data, we provide evidence of a low prevalence of nascent entrepreneurs and a small net employment contribution by high-growth firms. We admit that indisputable evidence for the effects of institutional arrangements is almost impossible to establish. However, the consistency of our theoretical arguments and empirical data makes a strong case for the notion that the Swedish case illustrates the costs of giving too little weight to economic renewal in policy making. 相似文献

Revealed preference tests are frequently used to check data on the behavior of agents for consistency with economic theory. Unfortunately these tests lack a stochastic element and thus one violation of revealed preference causes a rejection of the behavior being tested. To remedy this lack of a stochastic element in revealed preference analysis, we suggest a general, simple, and intuitive statistical procedure to test whether the observed number of violations is more consistent with a pre-specified type of non-degenerate behavior than with rational behavior. We illustrate this general procedure with an example using uniform random behavior that allows researchers to test whether the actual number of violations of revealed preference is more consistent with uniform random behavior than rational behavior. This statistical test takes advantage of the fact that nonparametric revealed preference tests involve known prices and expenditures. Our illustrative example is accompanied by some Monte Carlo exercises showing that the uniform test performs very well. We implement our test using datasets from two well-known economic experiments. One is a dataset on altruistic choices from Andreoni and Miller (Econometrica 70:737–753, 2002). The second is a dataset on the choices made by subjects who act within a token economy from Battalio et al. (West Econ J 11:411–428, 1973) and Cox (Econ J 107:1054–1078, 1997). We find that for a majority of subjects in one altruistic behavior sub-experiment uniform random behavior can be rejected in favor of rational behavior at the 10 % level of significance. For all but one subject, living in the token economy, uniform random behavior cannot be rejected. For that one subject in the token experiment uniform random behavior is rejected in favor of perverse economic behavior. 相似文献

Whilst much research has been conducted on decision support for electronic negotiations and some research has been done on communication support in this area, there is a lack of research on the interplay between these two elements of negotiations. The questions whether both are equally important, whether one effects the other, or whether they show counter-effects are important both for negotiation training (i.e. what should be the focus for becoming a good negotiator) and for system research (i.e. which system support elements need to be developed). The current paper presents results of a controlled laboratory experiment with negotiators that were provided with decision support and communication support and negotiators that had only communication support available. The impact of decision support on the communication process and on outcome dimensions as well as the impact of communication behaviour on the negotiation process and the qualitative dimensions of the outcome will be discussed. 相似文献

We argue that there is a connection between the interbank market for liquidity and the broader financial markets, which has its basis in demand for liquidity by banks. Tightness in the market for liquidity leads banks to engage in what we term “liquidity pull-back,” which involves selling financial assets either by banks directly or by levered investors. Empirical tests on the stock market are supportive. Tighter interbank markets are associated with relatively more volume in more liquid stocks; selling pressure, especially in more liquid stocks; and transitory negative returns. We control for market-wide uncertainty and in the process also contribute to the literature on portfolio rebalancing. Our general point is that money matters in financial markets. 相似文献

The paper investigates the validity of versions of discrete-time stochastic volatility models for index series known to contain component stocks exhibiting non-synchronous trading. The efficient method of moments (EMM) is used to fit versions of the discrete-time stochastic volatility (SV) model. The EMM methodology confronts moment conditions generated by a score generator (SNP) that are valid by construction. The moment generator suggests non-linearity in the index series. The EMM construction shows that a classical discrete time stochastic volatility model is rejected. An extended model incorporating an asymmetric volatility specification validates all the moment scores. Option values from Black and Scholes (BS) and Monte Carlo simulations (MC) seem significantly different. The results suggest that BS does not price asymmetry adequately. Asymmetry suggests increased market risk inducing higher BS call prices and lower (higher) BS put pricing for ATM and OTM options (ITM) relative to MC. 相似文献

Institutionalized pollution havens 总被引:1,自引:0,他引:1
A multiple-principal, multiple-agent lobby group model suggests that the effect of foreign direct investment (FDI) on environmental policies is conditional on the structure of host countries' political institutions such as the number of legislative units (veto players). The model also yields the novel concept of “aggregate honesty” which combines veto players and corruption. FDI raises environmental policy stringency where the number of legislative units are many (aggregate honesty is high), but reduces it where the legislative units are few (aggregate honesty is low). Our panel data evidence is fully consistent with these predictions. An additional contribution is to show the empirical importance of endogenizing environmental policy in Pollution Haven Hypothesis studies. Only when treated as endogenous does environmental policy have a significant negative effect on FDI. 相似文献

In this paper, innovation activities of a firm are observed as its R&D spending and participation in three categories of innovation systems. The various factors that can influence a firm's innovation efforts are divided into, (i) firm location reflecting the regional milieu and (ii) firm attributes such as corporate structure, nature of the knowledge production, type of industry and a set of specific firm characteristics. The study is based on information about 2094 individual firms, which may be non-affiliated or belong to a group (multi-firm enterprise). The empirical analysis applies a novel data set to examine the influence of location versus a vector of firm attributes. Among innovative firms, the location of a firm does not influence neither the R&D intensity nor the frequency of interaction in horizontal and vertical innovation systems, when controlling the skill composition, physical capital intensity, industry, firm size and market extension. The paper contributes to the literature by observing that innovative firms have similar characteristics irrespective of where they are located, although the share of innovative firms differs between regions. 相似文献
