Canada's approach to stabilization of the livestock industry differs from stabilization programs analyzed in recent economic literature. In theory, the Canadian approach results in net economic benefits to society. Empirical analysis of pork stabilization indicates the potential magnitude of net benefits and shows that alternative programs have different stabilizing characteristics.
L'approche Canadienne de stabilisation de la production animate diffère des programmes de stabilisation présentés récement dans la littérature économique. En théory l'approche Canadienne se traduit par un gain net au profit de la société. L'analyse empirique de la stabilisation du marché porcin indique l'eventail possible des gains net et montre que des variantes du programme ont diverses characteristiques de stabilisation. 相似文献

Demographers emphasize decreased mortality and “economic development” as the main contributors generating the demographic transition. Contrary to previous findings, we show that simple dynastic models à la Barro–Becker can reproduce observed changes in fertility in response to decreased mortality and increased productivity growth if the intertemporal elasticity of substitution is low enough. We show that this is largely due to number and welfare of children being substitutes in the utility of parents in this case. We find that with an IES of one‐third, model predictions of changes in fertility amount to two‐thirds of those observed in U.S. data since 1800. 相似文献

Although standard theories suggest that patent protection helps stimulate innovative activities, some new theories argue the opposite. Empirical studies do not generate conclusive results either. This paper investigates empirically the impacts of foreign patent reforms on innovation in the US, using data on successful patent applications in the US over 33 years and major IPR reforms in 21 countries, in addition to the patent reforms in the US and the TRIPS Agreement of the WTO. We find that the TRIPS Agreement has had significant impacts on innovation in the US, which highlights the importance of international cooperation in patent protection. However, the effects of strengthening patent protection by individual countries are not statistically significant. This result seems to imply that the US market is already sufficiently large/profitable to provide innovation incentives in the US and therefore further strengthening foreign patent protection simply increases the US innovators' rent, but not their innovation. 相似文献

We use a Barro–Becker model of endogenous fertility, in which parents are subject to idiosyncratic shocks that are private information (either to labor productivity or taste for leisure), to study the efficient degree of consumption inequality in the long run. The planner uses the trade-off between family size and future consumption and leisure, to provide incentives for workers to reveal their shocks. We show that in this environment, the optimal dynamic contract no longer features immiseration in consumption. We also discuss the implications of the model on the long run properties of family size in the optimal contract and show that the long run trend in dynasty size can be either positive or negative depending on parameters. 相似文献

This paper derives the dynamic programming equation (DPE) to a differentiable Markov Perfect equilibrium in a problem with non-constant discounting and general functional forms. Beginning with a discrete stage model and taking the limit as the length of the stage goes to 0 leads to the DPE corresponding to the continuous time problem. The note discusses the multiplicity of equilibria under non-constant discounting, calculates the bounds of the set of candidate steady states, and Pareto ranks the equilibria. 相似文献

This article investigates the effects of a large-scale public sector employment quota policy for disadvantaged minorities (Scheduled Castes and Scheduled Tribes) in India on their occupational choices, as defined by skill level, during the 1980s and 1990s. We find that, first, the employment quota policy significantly affects the occupational structure of both disadvantaged minority populations. In response to the employment quotas, individuals belonging to the Scheduled Caste group are more likely to choose high-skill occupations and less likely to choose low- and middle-skill occupations, while individuals belonging to the Scheduled Tribe group are less likely to choose high-skill occupations and more likely to choose low- and middle-skill occupations. Second, the impact of the employment quotas is significantly related with an individual’s years of schooling. Overall, the results indicate that the employment quota policy changes the occupational choices of individuals within the targeted populations and contributes to their improved socio-economic standing. 相似文献

We consider a horizontally differentiated duopoly where consumers care about the product's “greenness.” Firms can be asymmetric: they may differ in the product's intrinsic value and may also differ in their chosen level of greenness. We examine the choice of greenness and the implications of various policy interventions. We show that (i) the choices of product greenness are strategic substitutes, (ii) the high‐intrinsic quality firm produces the greener product, (iii) the low‐quality firm's greenness may increase with the cost of its provision or decrease with consumer willingness to pay for it, (iv) a minimum quality standard (MQS) leads the greener firm to lower its environmental quality and can even reduce average quality, (v) greenness is underprovided even if consumers fully internalize the externality, and (v) an MQS can reduce welfare if the greenness of the high‐quality firm exceeds the MQS, even when environmental quality is underprovided. The effects of policy interventions on profits differ qualitatively across polices and firms: A firm that lobbies for one type of intervention may lobby against another similar one, and a firm may lobby for an intervention while its competitor may lobby against it. A subsidy for the development costs of a green product can financially hurt both firms. 相似文献

Objectives:This study evaluated the effect of paliperidone palmitate long-acting injectable (LAI) antipsychotic on recovery-oriented mental health outcomes from the perspective of healthcare providers and patients during the treatment of patients with schizophrenia or schizoaffective disorders.Methods:Archival data for patients with a primary diagnosis of schizophrenia or schizoaffective disorder receiving ≥6 months of paliperidone palmitate LAI were retrieved from the electronic medical records system at the Mental Health Center of Denver. Mental health recovery was assessed from both a provider’s (Recovery Markers Inventory [RMI]) and patient’s (Consumer Recovery Measure [CRM]) perspective. A three-level hierarchical linear model (HLM) was utilized to determine changes in CRM and RMI scores by including independent variables in the models: intercept, months from treatment (slope), treatment time period (pretreatment and treatment), age, gender, primary diagnosis, substance abuse diagnosis, concurrent medications, and adherence to paliperidone palmitate LAI.Results:A total of 219 patients were identified and included in the study. Results of the final three-level HLMs indicated an overall increase in CRM scores (p?<?0.05), an overall increase (p?<?0.01), and an increased rate of change (p?<?0.05) in RMI scores during the paliperidone palmitate LAI treatment period vs the pre-treatment period.Limitations:This study contained a retrospective, non-comparative design, and did not adjust for multiplicityConclusions:The current study demonstrates that changes in recovery-oriented mental health outcomes can be detected following the administration of a specific antipsychotic treatment in persons with schizophrenia or schizoaffective disorders. Furthermore, patients receiving paliperidone palmitate LAI can effectively improve recovery-oriented outcomes, thereby supporting the drug’s use as schizophrenia treatment from a recovery-oriented perspective. 相似文献
