Using the gravity equation to differentiate among alternative theories of trade

The simple gravity equation explains a great deal about the data on bilateral trade flows and is consistent with several theoretical models of trade. We argue that alternative theories nevertheless predict subtle differences in key parameter values, depending on whether goods are homogeneous or differentiated and whether or not there are barriers to entry. Our empirical work for differentiated goods delivers results consistent with the theoretical predictions of the monopolistic-competition model, or a reciprocal-dumping model with free entry. Homogeneous goods are described by a model with national (Armington) product differentiation or by a reciprocal-dumping model with barriers to entry. JEL Classification: F10, F12
Equation de gravité et différenciation entre diverses théories du commerce international. La simple équation de gravité fournit une bonne part d'explication des flux de commerce bilatéraux et donne des résultats compatibles avec plusieurs modèles de commerce international. Les auteurs suggèrent que les diverses théories prédisent néanmoins des différences subtiles dans les valeurs de paramètres clés, selon que les biens sont homogènes ou différenciés, et qu'il y a barrières ou non à l'entrée. Le travail empirique des auteurs livre des résultats compatibles avec les prévisions théoriques du modèle de concurrence monopolistique ou du modèle de dumping réciproque avec entrée libre. On décrit les flux de biens homogènes à l'aide d'un modèle de différenciation nationale de produit à la Armington ou par un modèle de dumping réciproque avec barrières à l'entrée.     

Teams, Firms and the Evolution of Profit Seeking Behavior

Even as advances in information theory over the last quarter century have cast increasing doubt on the proposition that firms successfully maximize profits, the objective of profit maximization continues to be an axiomatic feature of the neoclassical theory of the firm. This paper attempts to improve our understanding firms by treating the objective function as an open question. Specifically, an ontogenetic thought experiment is undertaken to address the question of what differentiates production teams from firms by asking why team members would sell their control rights to a principal, thereby transforming the team into a firm. What results is an account of the emergence of the objective of profit seeking. Profit seeking emerges endogenously as a more fit alternative than the objective of value maximization, which is less capable of coping with uncertainty through purposive adaptation.     

Forensic Accounting and Fraud： Capability and Competence Requirements in Malaysia

The 2011 Global Economic Crime Survey instituted by PricewaterhouseCoopers （PwC） confirms the economic crime in Malaysia to be on the increase and, therefore, requires immediate attention to stem the tides. In anticipation of the challenges occasioned due to a shift from the modified cash basis to the accrual basis of accounting, the Malaysian State＇s determination to move from a developing nation to a developed nation, and to be ranked among the first 10 in 2020, this paper presents the need for forensic accountant and auditor capability （i.e., mindset and skills） on forensic accountant and auditor competence （i.e., task performance fraud risk assessment （TPFRA）） in the Malaysian public sector. It also draws the attention of the users of public sector accountants and auditors to the understanding of fraud mechanisms and how to deal with fraudsters. The population of this study comprised the accountants and auditors in the office of the Accountant General and Auditor General of Malaysia. The objective of this paper is to investigate the competence requirements of accountants and auditors in the effective and efficient utilization of capability requirements, which have the potentials to usher in the best global practices in fighting fraud in the Malaysian public sector.     

The value of information in a principal-agent model with moral hazard: The ex post contracting case

In a principal-agent model with moral hazard, a signal about the principal?s technology — the stochastic mapping from the agent?s action to the outcome — is observed before the contract is offered. The signal is either uninformative (null information), informative and observed only by the principal (private information), or also observed by the agent (public information). We show that, from an ex ante standpoint (before the signal is observed): (i) the agent prefers private to both null and public information; (ii) the principal sometimes prefers null to both private and public information; and (iii) when the principal prefers public to null information, she prefers public to private information, whereas the agent prefers private to public information. In this last situation, we also show that (iv) for any separating equilibrium with private information, there exists a contract with public information that both strictly prefer.     

Performance Measurement in Government Service Provision: The Case of Police Services in New South Wales

The NSW Government is implementing a financial framework which is designed to encourage government service providers to become more efficient and effective. NSW Treasury is using Data Envelopment Analysis (DEA) to measure the efficiency of major government service providers, such as police, courts and hospitals. This paper outlines the progress in implementing the new financial framework and illustrates the way NSW Treasury will use DEA to help improve the efficiency of government service providers by describing an analysis of the NSW Police Service. The results suggest that NSW police patrols (local police districts) could, on average, reduce input usage by 13.5 percent through better management, and by 6 percent if the patrols could be restructured to achieve the optimal scale. Results also indicate that differences in operating environments, such as location and socioeconomic factors, do not have a significant influence upon the efficiency of police patrols.     

Do Immigrants Affect Firm‐Specific Wages?*

We propose and test a novel effect of immigration on wages. Existing studies have focused on the wage effects that result from changes in the aggregate labour supply in a competitive labour market. We argue that if labour markets are not fully competitive, immigrants might also affect wage formation at the most disaggregate level – the workplace. Using linked employer?employee data, we find that an increased use of low‐skilled immigrant workers has a significantly negative effect on the wages of native workers at the workplace – also when controlling for potential endogeneity of the immigrant share using both fixed effects and instrumental variables.     

Gender, emotion and power in work relationships

We offer a theoretical account of how gender and emotion combine to influence the development of power in work relationships. We document the profound impact gender has on the display, perception and evaluation of emotion in the workplace. We illustrate the reciprocal relationship between emotion and power, and identify cycles of powerlessness that prevent women from developing and leveraging power in their work relationships. By exploring the nexus of gender, emotion and power in work relationships, we offer new insights into how the gendering of emotion creates and perpetuates gender differences in power in organizations. Implications for research and practice are offered.     

Competition, cooperation, and the neighboring farmer effect

In this paper we propose a model that explains how cooperation can emerge spontaneously between firms in a highly competitive market environment. The basic idea is that the more competitive is the market, the less costly it is for firms to help each other like good neighbors. Cooperation takes the form of sharing technical know-how, which speeds up the adoption of new technologies (normally developed elsewhere) that spur industrial development. The model comports with the development history of Japan's first example of successful industrial development – its cotton spinning industry – whose conditions match those of firms in small open economies today.
