Sectoral Technical Progress and Aggregate Skill Formation

Recent studies discuss micro-transmission mechanisms to measure spillover effects of MNC (Multinational Corporations) activity on human capital in host countries. We develop an aggregate transmission mechanism to show that technology deepening in advanced sectors affect economy-wide skill formation, not analyzed in previous studies. Sector-specific advanced technological input and borrowing from local capital market at preferential rates dampens rate of skill formation if local firms are more skill-intensive. Liberal trade policies applied only to MNC sector may lower traditional export if credit subsidy offered to MNCs is simultaneously withdrawn.     

Patent Enforcement, Innovation and Welfare

This paper analyzes how the Southern patent enforcement affects the Northern firm's choice of licensing, subsidiary production or exports for serving the Southern market, and the innovation rate in the North and ultimately the welfare in the South. We show that for imperfect patent enforcement, licensing contract leads to more innovation in the North relative to subsidiary or exports. When both subsidiary and exports are very costly options, no patent enforcement in the South is best for the South. However, when either subsidiary operation or exports can be organized cheaply, the Southern government chooses some positive degree of patent enforcement. We also establish that strengthening of patent enforcement in the South may lead to more licensing and less subsidiary operations or exports.     

The adoption of radical manufacturing technologies and firm survival

The emergence of dramatically innovative, or radical, new manufacturing technologies can force pivotal and life‐threatening decisions for industry competitors. These technologies can represent a huge cost for adopting firms, but may also offer the chance to achieve competitive advantage through superior manufacturing. While prior research has considered a range of production process decisions (e.g., JIT, mass customization) and outcomes for end‐product technologies, little attention has been given to adoption decisions relative to core manufacturing technologies. This study examines an industry's adoption of major manufacturing technologies over several decades and demonstrates that two groups of contingencies related to adoption (e.g., timing and cumulative effects) have a significant impact on firm performance. Based on a sample of over 1,000 firms, the results provide insights into the effects of adoption timing and ‘manufacturing technology bundles’ on firm survival. We also find that adoption of manufacturing technologies prior to the inflection point of the estimated Bass diffusion curve for each technology leads to significant reduction in firm mortality. Thus, we are able to demonstrate the ability of the Bass model to predict the survival outcomes of firms facing manufacturing technology adoption decisions. The strategic implications of these pivotal decisions are considered. Copyright © 2008 John Wiley & Sons, Ltd.     

Resilient Growth: Fantasy Plans and Unplanned Developments in India's Flood‐Prone Coastal Cities

Academic and policy literatures on urban climate resilience tend to emphasize ‘good planning’ as the primary means for addressing the growing risk of flooding in Asia's coastal megacities. Cities have come to rely on disaster and climate resilience plans to future‐proof their landscapes and protect vulnerable populations. Yet while data is collected, models are built and plans are drafted, environmentally destructive development practices continue unabated and often unchallenged. This article examines and seeks to explain the contradictions between a growing awareness of the risks of climate‐induced flooding in resilience plans and the continuation of development practices widely acknowledged to exacerbate those risks. It analyzes these contradictions in the context of Mumbai and Kolkata, India's largest coastal cities, which are facing the severest threats from climate‐induced flooding. Based on analyses of key resilience planning documents and both planned and unplanned developments in some of Mumbai's and Kolkata's most ecologically sensitive areas, our analysis reveals that resilience planning, promoted by the central government and international consultants, and presented in locally produced ‘fantasy plans’, fails to address the risks of climate‐change‐related flooding owing to tendencies to sidestep questions of politics, power and the distributional conflicts that shape urban development. We conclude that efforts to reduce urban flood risk would benefit from the research, methods and analytic concepts used to critically study cities, but significant gaps remain between these fields.     

Robust analysis of longitudinal data with nonignorable missing responses

We encounter missing data in many longitudinal studies. When the missing data are nonignorable, it is important to analyze the data by incorporating the missing data mechanism into the observed data likelihood function. The classical maximum likelihood (ML) method for analyzing longitudinal missing data has been extensively studied in the literature. However, it is well-known that the ordinary ML estimators are sensitive to extreme observations or outliers in the data. In this paper, we propose and explore a robust method, which is developed in the framework of the ML method, and is useful for downweighting any influential observations in the data when estimating the model parameters. We study the empirical properties of the robust estimators in small simulations. We also illustrate the robust method using incomplete longitudinal data on CD4 counts from clinical trials of HIV-infected patients.     

EXISTENCE OF THE STANDARD SYSTEM IN THE MULTIPLE‐PRODUCTION CASE: A SOLUTION TO THE MANARA PROBLEM

In this paper we show that the Manara problem in the case of Sraffa's generalized multiple‐production case arises due to the presence of superfluous processes of production. We argue that ‘goods’ should be defined from the perspective of the system and not the observer. We provide a mathematical procedure to remove superfluous processes from the construction of Sraffa's Standard system. Once this is done, the Manara problem disappears.     

Auditor Independence: A Nonparametric Test of Differences Across the Big‐5 Public Accounting Firms

This small sample study provides additional evidence on the unsettled question of auditor independence: Does the provision of non‐audit services by an auditor compromise independence resulting in a poor quality audit? We also examine whether these findings vary across the “Big‐5” public accounting firms. Most prior studies addressing this question, using parametric approaches and various measures of audit quality, have reported conflicting results. Contrary to these studies, we use a non‐parametric approach and the probability of GAAP violation as a new measure of audit quality to address this question. Using data from a sample of Fortune 500 companies for the year 2000, we find that firms whose auditors provide substantial non‐audit services tend to have a higher propensity to violate GAAP. At the firm‐level analysis, we find that these results are more likely driven by few of the Big‐5 public accounting firms. For the remaining firms, the association between non‐audit services and quality of audit could not be established, primarily because of small sample size and lack of power in the test. Our main finding is consistent with other recent studies that provide evidence that the rendering of significant non‐audit services by auditors creates conflict of interest resulting in poor quality audits. Furthermore, our result of differences in these levels of association among the Big‐5 accounting firms represents a new finding, and suggests that there is a need for controlling them separately in research studies examining auditor independence.
