Supply network capacity planning for semiconductor manufacturing with uncertain demand and correlation in demand considerations

A semiconductor supply network involves many expensive steps, which have to be executed to serve global markets. The complexity of global capacity planning combined with the large capital expenditures to increase factory capacity makes it important to incorporate optimization methodologies for cost reduction and long-term planning. The typical view of a semiconductor supply network consists of layers for wafer fab, sort, assembly, test and demand centers. We present a two-stage stochastic integer-programming formulation to model a semiconductor supply network. The model makes strategic capacity decisions, (i.e., build factories or outsource) while accounting for the uncertainties in demand for multiple products. We use the model not only to analyze how variability in demand affects the make/buy decisions but also to investigate how the correlation between demands of different products affects these strategic decisions. Finally, we demonstrate the value of incorporating demand uncertainty into a decision-making scheme.     

Determinants and Relationships in Sectoral Trade: A Bilateral Model for Knitwear Clothing

The generalized aggregated trade models do not capture the industry or product‐specific competitive situation and overgeneralize the bilateral cases. As a result, product‐specific trade determinants at the sectoral or bilateral level cannot be sufficiently drawn from such generalized models. This holds true for knitwear clothing products, an important component of international textile trade. To remedy this, we propose a sector‐specific bilateral model in the context of knitwear clothing exports from India to the United States. This pair of countries is chosen due to unilateral trade flows as well as to underline the contrasting features of developed north versus developing south. The vector autoregression (VAR) model was found more appropriate than other available modeling choices. We used monthly frequency data from January 2006 to December 2012. The traditional determinants such as exchange rate and price competitiveness remain relevant. Chinese competition emerges as a significant determinant, which underlines the relevance of a sector‐specific bilateral trade model. The 2009 recession showed a clear impact, albeit for only a few months. Our model is parsimonious but has more explanatory power than generalized models. Policy researchers may further explore the model for more fine‐tuned policy on sector‐specific factors. © 2016 Wiley Periodicals, Inc.     

Economic reforms,growth and well-being: evidence from India

This study examined economic well-being of sub-national units in India since the economic reforms. For this purpose, the study constructed well-being index for 17 major states of India for the period 1981–2011 based on five broad dimensions. Our results showed that the economic well-being of states has declined since the reforms. The interstate disparities have increased and the states (except Punjab and West Bengal) which performed well prior to the reforms continued to perform well in the post-reform years too. In addition, our regression results for the high well-being and low well-being states revealed that the reforms have benefited more developed high well-being states, rather than low well-being states. While human capital was found significantly and positively related to per capita incomes in both groups of the states, financial development was positively related in high well-being states, but a negative association was visible in the low well-being states.     

Growth of the Electronic Commerce in China and India: A Comparative Study

This article compares the growth of e-commerce in China and India by identifying factors that act as driving forces and barriers to this progress. A comparative study of Internet development in the two countries reveals that although China was connected to the Internet much later than India, it is now far ahead of its Asian rival due to the implementation of several ingenious “Golden Projects” and the rapid development of Chinese Internet infrastructure. Nevertheless, there are many shared sociocultural factors that affect the spread of their e-commerce equally. Despite many barriers, the future of e-commerce in both countries appears bright.     

Ownership,competition, and bank productivity: An analysis of Indian banking in the post-reform period

This paper investigates the effect of ownership and competition on Indian bank productivity since the 1991 reforms. We find that Indian private banks dominate the public and foreign banks both in terms of productivity levels and productivity growth, with the new Indian private banks leading the charge. Competition has a positive impact on productivity for the old Indian private banks, and all the other banks are hurt by competition — the worst hit being new Indian private banks. A similar picture emerges on the productivity growth side, with the new Indian private bank productivity growth being the worst affected as competition increases. An analysis of the pre- and post-1998 periods shows that the latter period displays a much higher productivity gap between the Indian private banks and the public and foreign banks. Indian private bank productivity and productivity growth suffer due to increasing competition in the post-1998 period.     

Balance Sheet Effects, Growth, and Crises

This paper addresses two questions: are currency crises predicted by increases in a central bank’s external and contingent liabilities relative to assets, and do these “balance sheet effects” generate persistent output losses following a crisis? I find empirical evidence that the answer to both questions is yes. I use data on stocks of gross external assets and liabilities for 167 countries over 1973–2003, in an unbalanced panel probit regression to obtain robust estimates of the probability and determinants of a post‐crisis recession. Several single and simultaneous equation specifications support the idea that the output cost of a currency crisis depends on its transmission mechanism. Specifically, a recession is likely to be severe if it is preceded by a crisis that works its way through the financial sector. In addition, the results show that measures of contingent liabilities, capital flight, and lack of financial depth are significant predictors of costly crises.     

Influences of question wording on levels of support for genetically modified organisms

This paper examines the influences of question wording on consumers’ levels of support for genetically modified organisms (GMOs) in food products. Pairs of questions, offering varied amounts of information on the benefits and risks of GMOs, are posed to consumers in a specific geographic area (Vermont, USA) to ascertain the factors that impact on levels of support for this technology. A multivariate analysis is conducted to examine how knowledge, attitudes, and behavioural intentions affect changes in levels of support. The findings suggest that consumers’ levels of support do vary based on question wording. It is further found that knowledge and behavioural intentions play a consistently significant role in influencing change in support for GMOs. Implications for both consumer advocacy groups and industry groups are discussed.     

Banking in the Shadows: A Comparative Study of China and India

In recent years there has been increasing interest in the rise of shadow banking in China and India. In this paper, we aim to get a better understanding of the differences in trends and investigate the factors leading to the increase of shadow banking in these two major emerging economies. We find that financial exclusion is a common factor leading to the growth of shadow banking in both countries. While financial reform has taken place in India, financially repressive policies still prevail in China. Although several regulatory measures have been adopted in India and China, the size of the shadow banking sector in these two countries remains underestimated. Thus, streamlining and enhancing data collection is a key priority for both nations. We argue that regulation in both countries should be more activity focused (specific field in which a shadow bank is focused on) rather than sector or entity based, and it should be at par with banks. The shadow banks provide last mile connectivity to remote, distant, and ignored segments of the population not serviced by the formal financial sector. As this enhances financial inclusion, a balanced approach is required keeping in view both costs and benefits of the shadow banking system.     

The budget impact of brodalumab for the treatment of moderate-to-severe plaque psoriasis on US commercial health plans

Introduction: Brodalumab is a new biologic approved by the US Food and Drug Administration in 2017 for the treatment of moderate-severe psoriasis. This study evaluated the impact of the introduction of brodalumab on the pharmacy budget on US commercial health plans.

Methods: An Excel-based health economic decision analytic model with a US health plan perspective was developed. The model incorporated published moderate-to-severe psoriasis prevalence data; market shares of common biologic drugs, including adalimumab, ustekinumab, secukinumab, ixekizumab, and etanercept, used for the treatment of moderate–severe psoriasis; 2017-year Wholesale Acquisition Costs for the biologic drugs; drug dispensing fee; patient co-pay; and drug contracting discount. Total annual health plan costs for the biologic drugs were estimated. Scenarios with different proportions of patients treated with brodalumab were compared to a control scenario when no brodalumab was used.

Results: In a hypothetical commercial health plan covering two million members, 7,038 moderate-to-severe psoriasis patients were estimated to be eligible for treatment with brodalumab. Prior to brodalumab approval, the proportions of patients treated by other biologics were estimated at 50.8% for adalimumab, 13.5% for ustekinumab, 14.1% for secukinumab, 4.4% for ixekizumab, and 17.2% for etanercept. With a 20% drug price discount applied to all biologics, the annual health plan costs for brodalumab, adalimumab, ustekinumab, secukinumab, ixekizumab, and etanercept were estimated at $37,224, $49,166, $55,084, $56,061, $64,396, and $57,170, respectively. When no brodalumab is used, the total annual pharmacy budget for the biologics used among these patients was estimated at $414,362,647. Among scenarios where the proportions of brodalumab usage were 3%, 8%, 16%, and 30%, the total annual pharmacy cost was estimated to be reduced by $3,698,129, $9,861,677, $19,723,355, and $36,981,290, respectively.

Conclusion: Based on the economic model, brodalumab has the potential to substantially reduce pharmacy expenditures for the treatment of patients with moderate-to-severe plaque psoriasis in the US.
