Domestic technology,consumption economies of scale and poverty: evidence from Sri Lanka

While it is well known that new technologies enhance consumer welfare, the manner in which these technologies impact the ability to realize economies of scale in consumption is not well understood. We use Sri Lankan household data to examine how the adoption of new technologies by households positively impacts their ability to achieve household economies of scale. This suggests that new technologies not only deliver a greater variety of consumption goods to consumers, but they may also play an important role in enabling large households to escape poverty by lowering the per-capita costs of maintaining a given standard of living. Given the importance of consumption economies of scale in the measurement of poverty, this study provides some insights on the extent to which the number of poor households changes when food consumption scale economies due to technology adoption in the domestic sphere are incorporated.     

The effects of climatic variation on rice production in Sri Lanka

We study the responsiveness of rice production to climatic variation using a recent pseudo-panel data set from Sri Lanka. Output per farm is modelled as a non-linear function of temperature and rainfall (and other standard controls) using fixed effects regressions. We find that both climatic variables have concave, non-monotonic effects upon production, and that output is close to maximized at current climatic values. This implies that variations in growing conditions are likely to have negative effects upon production. Random simulations are used to model these impacts under various climate change scenarios, and we find that increasing temperatures will adversely affect rice production much more than varying rainfall, although the effects of a small ceteris paribus rise in temperature are positive. As rice production is a key component in economic output for Sri Lanka and other developing countries, our results have implications for food policy and poverty management in the future.     

Growth Patterns and Inequality in the Presence of Costly Technology Adoption

The stylized facts that motivate this article include the diversity in growth patterns that are observed across countries during the process of economic development and the divergence over time in income distributions both within and across countries. We construct a dynamic general equilibrium model in which technology adoption is costly and agents are heterogeneous in their initial holdings of resources. We interpret the adoption cost as the resources expended in acquiring skills associated with new technologies. Endogenous growth occurs in our model largely as a result of human capital deepening. The analytical results of the model characterize three growth outcomes associated with the technology adoption process depending on productivity differences between the technologies. These outcomes are labeled ‘poverty trap,’ ‘dual economy,’ and ‘balanced growth.’ The model is then capable of explaining the observed diversity in growth patterns in addition to the divergence of incomes over time and across countries.     

On the diffusion of toilets as bottom of the pyramid innovation: Lessons from sanitation entrepreneurs

There is an emerging body of literature on product innovations for the poor at the bottom of the income pyramid. However, there is little on why delivery systems succeed or fail in this context and the present paper attempts to fill this void by examining why and how sanitation entrepreneurs are succeeding in India to diffuse toilets — an innovation for rural households, which never had access to one before. The literature is analyzed and confronted with the actual field practices. We demonstrate that the common thread that unifies progressive sanitation entrepreneurs is their adoption of a ‘market based approach’. There are market failures stemming from the demand side due to problems in expression of demand and its mismatch with the perceived value of the innovation. In response, sanitation entrepreneurs go beyond the standard linear model of assessing need and appropriateness of technology. They create innovations in ‘technological design’ as well as in the ‘delivery platforms’ to include practices for ‘accompaniment’, ‘sustainable maintenance’ and ‘generation of knowledge'. Thus, they make-up for sluggish or missing markets and informational asymmetries to ensure sustained use of toilets.     

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.     

Technological competence and the influence of networks: a comparative analysis of new biotechnology firms in france and britain

The objective of this paper is to examine the role of external networks not only as a resource but also as a constraint for the evolution ofthe technological competence of twenty new biotechnology firms (NBFs) in France and Britain. The analysis is bared on extensive interviews conducted with the Chief Executive Officers (CEOs) of twenty NBFs, ten in France and ten in Britain. The paper identifies the network structures ofthe tweng NBFs and the impact of netmorks on the evolution of their technologial competence. The paper also attempts to identify the differences between NBFs in France and Britain in terms of the framework developed. It clearly illustrates that the capacity of NBFs to construct appropriate external linkages with other firms andfinanckrs is crucial to their success.     

Country-Specific Characteristics of Patent Applications in France, Germany and the UK in the Biotechnology Sectors

Given that institutions are highly country-specific, the differences in the national systems of innovation in the different countries of Europe are likely to give rise to country-specific patterns in new technology investment. The objective of this paper is to identify such differences, in the biotechnology sectors, in France, Germany and the UK. The results, based on an analysis of patent applications, indicate that France is focused on the 'dominant' technology of genetic engineering and its public laboratories and collective patent applications play an important role. Germany is leading in the total number of patent applications but is focused on 'intermediate' and 'residual' technologies with a significant number of individual depositors. The UK is leading in the 'dominant' technology. Its public laboratories and firms are strongly involved in depositing patents with a marked strategy of international protection.     

Does asymmetry in price transmission exist in the rice market in Sri Lanka?

This study analyses asymmetry in price transmission between wholesale and retail rice markets in Sri Lanka, using the threshold autoregressive model. We found that the wholesale and the retail rice markets in Sri Lanka are integrated, with price changes moving from the wholesale to the retail market. However, the price transmission process is asymmetric. In particular, price increases at the wholesale market transmit immediately to the retail market while price decreases transmit more slowly. Parameter stability test and follow-up analysis indicated that the price transmission process is asymmetric only during periods of price surges, suggesting that the rice market is not efficient during these periods.
