An exploratory study of product development in emerging economies: evidence from medical device testing in India

Recent research has studied innovation in emerging economies. However, microlevel product development processes in these economies are relatively unexplored, and the mechanisms by which the emerging economy context might affect such processes are still unclear. In this paper, we explore the testing routines fundamental to product development in one emerging economy. Based on an exploratory field study of medical device development projects in India, we observe the frequent, iterative testing of prototypes in clinical settings and investigate the related learning process. The observed testing approach is distinctly different from the comparatively linear and sequential approach adopted by medical device development teams in developed countries like the United States. Further, we suggest that such testing is feasible in India because of the prevailing regulatory flexibility, the cognitive orientation of device development practitioners and the normative orientation of medical professionals.     

Forecasting Nevada gross gaming revenue and taxable sales using coincident and leading employment indexes

This article provides out-of-sample forecasts of Nevada gross gaming revenue (GGR) and taxable sales using a battery of linear and non-linear forecasting models and univariate and multivariate techniques. The linear models include vector autoregressive and vector error-correction models with and without Bayesian priors. The non-linear models include non-parametric and semi-parametric models, smooth transition autoregressive models, and artificial neural network autoregressive models. In addition to GGR and taxable sales, we employ recently constructed coincident and leading employment indexes for Nevada’s economy. We conclude that the non-linear models generally outperform linear models in forecasting future movements in GGR and taxable sales.     

Mixed markets in bilateral monopoly

Should we expect to see patterns in the privatization of a public bilateral monopoly? To address this question, the paper analyzes the welfare implications of privatization and examines the interplay of firm location in the vertical stream, differential priorities on private and public profit in welfare and cost asymmetries in a mixed bilateral monopoly. We conclude that merely comparing cost savings from privatization upstream/downstream, is inadequate. If public profit is relatively insignificant in welfare, then only relative cost savings matter. However, if public profit is sufficiently important, then privatization downstream will maximize welfare if it is as (or more) cost effective compared to privatization upstream. We find that downstream privatization can be better than upstream privatization even when the latter is more cost effective than the former.     

Convergence and reorientation via open innovation: the emergence of nutraceuticals

The use of networked organisational arrangements to conduct exchanges is one of the most distinctive features of high-tech research-intensive industries. Advances in biotechnology and genomics research have enabled a generic technology platform that has fuelled a more ‘open’ approach to innovation and learning. This relies on collaborations between networked partners and allows for the convergence and reorientation of traditional sectors. This paper lends support to the view that some technologies can trigger a higher system level innovation, that is, in addition to the inter-firm level, an inter-industrial and inter-institutional level convergence and re-orientation process. This paper explores how this phenomenon is being witnessed in the pharmaceutical and food sectors and fast becoming a dominant logic in the emerging nutraceuticals industry.     

Product development,imitation and economic growth: A note

Abstract

A dynamic North – South general equilibrium model of international product cycle is presented in this paper. The qualitative effects of strengthening intellectual property rights (IPR) on the balanced growth rate of the world economy is studied in two alternative cases: (i) imitation is direct from North to South; (ii) multinationalization is the channel of product transfer.     

Optimal Duration of Promotion for Durable Technology Product in a Segmented Market

ABSTRACT

Firms develop segment driven promotional mix to target its potential customers selectively. As the marginal revenues from promotion decreases with time, it is important to determine the optimal stopping time of a promotional activity. In the literature, the studies carried in this domain do not consider market segmentation and assume a uniform promotional mix. In this study, alternative decision models are developed to determine the duration of promotion for a durable technology product applicable to a segmented market. A case study is discussed to validate the proposed models and to illustrate the solution methodology based on a differential evolution algorithm.     

Demand for Crop Insurance in Developing Countries: New Evidence from India

Determining farmers’ real demand for crop insurance is difficult, especially in developing countries, where there is a lack of formal financial sector integration and a high reliance on informal risk mitigation options. We provide some new estimates of farmers’ willingness‐to‐pay for insurance in the context of a large‐scale subsidised programme in India. We conducted a discrete choice experiment with agricultural households across four states in India, enabling us to estimate preferences for specific insurance policy attributes such as coverage period, method of loss assessment, timing of indemnity payments and the cost of insurance. Our results suggest that farmers do value crop insurance under certain conditions and some are willing to pay a premium for such coverage in excess of the subsidised rates they are currently required to pay under this programme. In particular, farmers value the assurances that they will receive timely payouts when they incur losses, and may not have a strong preference for the method with which losses are assessed. On the other hand, farmers are quite sensitive to coverage periods. Our baseline assessment shows that when optimised to farmer requirements, there can be a sizeable demand for crop insurance by developing country farmers.     

Time–frequency relationship between US inflation and inflation uncertainty: evidence from historical data

We provide new evidence on the relationship between inflation and its uncertainty in the United States on an historical basis, covering the period from 1775 to 2014. First, we use a bounded approach for measuring inflation uncertainty, as proposed by Chan et al. (2013), and compare the results with the Stock and Watson (2007) and Chan (2015) methods. Second, we employ the wavelet methodology to analyze the comovements and causal effects between the two series. Our results provide evidence of a relationship between inflation and its uncertainty that varies across time and frequency. First, we show that in the medium and long runs, the Freidman–Ball hypothesis holds with a bounded measure of uncertainty, while if the Stock and Watson (2007) measure of uncertainty is used, the Cukierman–Meltzer reasoning prevails. Therefore, the findings are sensitive to the way inflation uncertainty is computed. Second, we discover mixed evidence about the inflation–uncertainty nexus in the short run, findings that explain the mixed results reported to date in the empirical literature.     

Dynamic Comovements Between Housing and Oil Markets in the US over 1859 to 2013: a Note

In this study, we examine the dynamic comovements between housing and oil market returns in the United States over the period 1859–2013, while controlling for real gross domestic product growth, inflation, interest rates, and real stock, gold and silver returns that are known to affect both these markets. As such, we provide a bird’s-eye view on the interdependencies between these two markets from a historical perspective. The results of our empirical analysis reveal that comovements between housing and oil market returns are consistently negative over time, apart from several recessions the U.S. economy experienced in the 19th century, wherein correlations were positive.     

Where have all the brides gone? Son preference and marriage in India over the twentieth century

Marriage is universal for women in India, but the marriage rate for men varies across regions, where the region is a proxy for shared cultural norms. A preference for sons results in a biased sex ratio towards men and creates a shortage of brides in the marriage market. Using the Indian census of 1931, the article finds that son preference was a regional phenomenon and led to a low marriage rate for men. Using caste‐level information, the article finds no evidence that men from the upper castes enjoyed an advantage in the marriage market as the theoretical literature predicts. The regional differences in gender bias and marriage market outcomes have persisted over the twentieth century and indicate the persistence of cultural values. The long‐run changes show that the marriage squeeze has reduced the surplus of men in all regions; however, the regional differences in son preference and marriage outcomes were still the same in 2001.
