Biodiversity Conservation and Productivity in Intensive Agricultural Systems

This paper explores the economic effects of biodiversity loss on marketable agricultural output for intensive agricultural systems, which require an increasing level of artificial capital inputs. A theoretical bio‐economic model is used to derive a hypothesis about the effect of the state of biodiversity on the optimal crop output both in the longer run and in the transitional path towards the steady‐state equilibrium. The hypothesised positive relationship between biodiversity stock and optimal levels of crop output is empirically tested using a stochastic production frontier approach, based on data from a panel of UK specialised cereal farms for the period 1989–2000. The results support the theoretical hypothesis. Increases in biodiversity can lead to a continual outward shift in the output frontier (although at a decreasing rate), controlling for the relevant set of labour and capital inputs. Agricultural transition towards biodiversity conservation may be consistent with an increase in crop output in already biodiversity‐poor modern agricultural landscapes.     

Porter's Model of Generic Competitive Strategies

A firm’s competitive behavior is an important topic for practitioners, theorists, and policy makers. Among the explanations of firms’ behavior is Michael Porter’s model. We have presented this model along with some alternative approaches: Structure-Conduct-Performance, the New Industrial Organization and Game Theory, the Resource-Based Perspective, and Market Process Economics. These approaches are discussed in terms of their relations, similarities, and differences relative to Porter’s model. In our comparative discussion, we support the use of Porter’s model to evaluate firms’ competitive behavior. Our reasons for this support are this model’s popularity, well-defined structure, feasibility, clarity, simplicity, generality, and its complementarity to two other main approaches. We find the Porter model to be a convenient approach to the firm’s competitive advantage and strategy. This article draws on the thesis that Orges Ormanidhi wrote for his Masters of Philosophy from Staffordshire University.     

Minimum tax legislation and its effect on corporate financial reporting: A comparative analysis between US and India: a discussion

In this study, the authors investigate imposing a minimum alternative tax (MAT) on Indian corporations during the 1996–1997 budget years. The authors have two objectives: to assess the new legislation's impact on tax revenue, and to determine how corporations responded to its imposition because of its explicit link to financial reporting. They first assess whether, on average, firms with low estimated tax rates before the imposition paid higher taxes after imposition and find, overall, that corporations paid, in total, a greater amount of their income in taxes. They also find that the largest firms in their sample experienced a smaller increase in their effective tax rates than smaller firms did. Next, they assess whether MAT-affected firms altered their financial statement reporting to reduce exposure to the MAT. Specifically, they assess whether a greater portion of MAT-affected firms changed their financial statement depreciation policies than non-MAT-affected firms. They report that, for their sample, a significant number of MAT-affected firms increased their depreciation rate after MAT imposition. The proportion of non-MAT-affected firms changing depreciation rates after imposition was not significant. They also partition MAT- and non-MAT-affected firms on increasing or decreasing book profit and find that MAT-affected firms made proportionally more changes. The authors conclude that the MAT appeared to have increased horizontal equity among taxpayers in India, but its tax revenue enhancement potential is limited by its scope, limited applicability, and avoidance behavior by affected corporations. My comments are directed at what I perceive to be motivational and methodological issues in the paper and the conclusions we can draw from the current representation.     

An Efficiency Enhancing Minimum Wage

We consider an economy with a tax on all labor earnings. We discover that a slightly binding minimum wage on one sector can enhance efficiency. The minimum wage attracts high‐reservation wage workers into the minimum‐wage sector. If the labor demand curve in the free sector is quite flat, the vast majority of workers displaced by the minimum wage find employment in the free sector, raising aggregate employment. This displacement of workers by the only slightly binding minimum wage has negligible effects on efficiency. So efficiency and tax revenue rise as the minimum wage pulls labor out of untaxed leisure, where too much of the labor force is lurking, into taxed work.     

Does Trade Liberalization Benefit Young and Old Alike?

In an overlapping generations model, capital and labor produce two tradable goods. A kleptocratic government spends the tariff revenue. Trade liberalization benefits the retired generation if and only if the relative price of the capital-intensive good rises. Starting from autarky, a small liberalization benefits subsequent generations if and only if it hurts the retired one, a result reminiscent of the Stolper-Samuelson theorem. However, the terms-of-trade effect means a large liberalization may simultaneously raise the welfare of all generations.     

Trade liberalization and capacity utilization: New evidence from the Turkish rubber industry

This study empirically tests the hypothesis that trade liberalization increases capacity utilization. It calculates capacity utilization for the Turkish rubber industry by using a production theory framework. More specifically, plant-level capacity utilization levels are calculated using a Generalized Leontief cost function system. Capacity utilization levels were low but improved when the trade regime shifted from a restrictive to a more liberalized one. The size and location of plants were two significant factors which created capacity utilization differences within the industry. However, capacity utilization levels appeared to improve primarily because of trade liberalization.Also, a scholar-in-residence, Department of Economics, Duke University.

Corporate Social Responsibility and Ethical Leadership: Investigating Their Interactive Effect on Employees’ Socially Responsible Behaviors

This research investigates the interlinkage between corporate social responsibility (CSR) and ethical leadership in inducing employees’ socially responsible behaviors (SRBs). Specifically, building on organizational identification theory and cue consistency theory, we develop and test an integrated moderated mediation framework in which employees’ perception of ethical leadership moderates the mediating mechanism between their perceptions of CSR (i.e., perceived CSR–environment and perceived CSR–community), organizational identification, and SRBs (i.e., green and societal behaviors). The findings highlight the need for consistency between employees’ perceptions of CSR and ethical leadership to foster their propensity to further social good through relationship-building activities with their organization. The results, which largely verify the theoretical framework, contribute to and have implications for both research and practice.     

How Do Audit Offices Respond to Audit Fee Pressure? Evidence of Increased Focus on Nonaudit Services and their Impact on Audit Quality

We investigate whether audit offices respond to audit fee pressure by increasing their focus on nonaudit services (NAS), as well as the combined effect of audit fee pressure and an increased focus on NAS on audit quality. We find a positive association between audit fee pressure and changes in NAS at the audit office level. We also find increased rates of client misstatement among audit offices that increase focus on NAS in the presence of audit fee pressure compared to audit offices that do not, suggesting a joint effect on audit quality. We find that the reduction in audit quality occurs in large audit offices. Overall, we provide evidence that audit offices’ provision of additional NAS in the presence of fee pressure is an important dimension to consider when examining the effects of declining audit fees on audit quality.
