This study examines the sustainability along with the structural stability of the U.S. federal budget deficit over the post
World War II period. Allowing for an endogenously determined structural break in 1982:1, tests of unit roots based on Perron's
[1997] methodology suggest a stationary and sustainable budget deficit. Moreover, threshold autoregressive and momentum threshold
autoregressive models do not detect asymmetries in the response of the budget deficit to deviations from its long-run trend. 相似文献

In a monopolistic competition macromodel with endogenous market structure, the fiscal multiplier is shown to consist of two components. The first depicts the response of output to a fiscal expansion through the conventional channels that disregard the role of market imperfections. The second component captures the effects of firms' market power as well as the policy-induced change in market structure. The latter effect—which has not been taken into account in existing studies—is shown to be quite significant in raising the fiscal multiplier (even above unity) and in improving consumers' welfare when the labour market is competitive. 相似文献

Empirical analysis, based on a general dynamic Almost Ideal Demand System, shows the commonly used autoregressive and partial adjustment processes are restrictive to meat demand data. This study derives a linear specification in levels form to investigate dynamics in a general framework. Merging a long-run steady state structure with short-run dynamics results in consistent and robust long-run demand elasticities Une analyse empirique, basée sur un systéme dynamique général de demande quasi optimale, montre que les mécanismes courants d'ajustement autorégressif et d'ajustement partiel ont un effect restrictif sur l'évaluation des données de la demande de viande. Les auteurs proposent une spécifcation linéaire par niveaux pour examiner la dynamique du cadre général. La combinaison d'une structure stable de longue durée avec une dynamique de courte période a produit des élasticités cohérentes et solides de la demande à long terme 相似文献

Abstract. We study the profitability of horizontal mergers in a dynamic competition context with sticky prices. It is shown that, when firms use open‐loop strategies, a merger is profitable only if the share of the market that merges is significant enough. In the case where firms use closed‐loop strategies we provide a method to conduct analytically the study of the profitability of horizontal mergers. We first prove the existence of an equilibrium of the game when a subset of firms merges. When firms use feedback strategies, mergers are profitable even when the share of the market that merges is arbitrarily small. JEL Classification:D4, L13 相似文献

This study examines an extended version of the Theory of Planned Behaviour (TPB) in the context of nicotine replacement therapy (NRT) as an aid to smoking cessation. An attempt is made to address the intention–behaviour gap identified in the literature by specifically focusing on the role and interrelationships of volitional stages, namely intention, planning and anticipated effort. A convenience sample of 207 female smokers, aged 16–36, provided information about their views, attitudes and volitional behaviour regarding the use of NRT as an aid to smoking cessation. Results of this study show the TPB to be pertinent, accounting for 41% of the variance in intention to use NRT as an aid to smoking cessation. Furthermore, behavioural intention is found to mediate the relationship between the TPB antecedents (attitude, subjective norm and perceived behavioural control) and each of the two volitional elements, planning and anticipated effort. The implications of these findings are discussed. 相似文献

This study examines the value of voluntary and mandatory disclosure in a market that applies International Accounting Standards (IAS) with limited penalties for non compliance. The lack of enforcement creates an element of choice in the level of mandatory disclosure by companies. Using panel-data analysis, our empirical results show that, after controlling for factors such as asset size and profitability, mandatory disclosure has a highly significant but negative relationship with firm value. This result, although puzzling from a traditional perspective, is consistent with the predictions of analytical accounting models, which emphasize the complex interplay of factors determining disclosure effects. Our results also show that voluntary disclosure has a positive but insignificant association with firm value. This lack of statistical significance supports the view that there is a complex interplay of different factors determining the relationship between disclosure and firm value. 相似文献

The design of a single product manufacturing system with assembly is considered. The processing is on a lot-by-lot basis with the lot size fixed. The decision variables include interrelated single sampling plans, manufacturing process quality levels, incoming raw material quality levels and assembly process quality levels. A solution procedure is given to minimize the expected total of the costs associated with the quality of the finished product subject to a limit on the Average Outgoing Quality Limit of the finished product. An example is provided. 相似文献

This paper obtains an expression of the bias when relevant explanatory variables are omitted in seemingly unrelated regression (SUR) models. A simple demand system is provided to illustrate the direction of the bias terms when a variable is omitted.
L'article permet d'exprimer le biais qui résulterait de l'omission de variables explicatives pertinentes dans des modéles de régression sans corrélation apparente (SUR). Le système de demande simple qui est présente ici met en évidence le sens des éléments de biais lorsqu'on omet une variable. 相似文献

A sufficient condition for D-stability of an n × n matrix A is the existence of a positive diagonal matrix P such that PA + A′P is negative definite. The search for P is replaced by solving a convex minimization problem. 相似文献
