Property rights imperfections and asset allocation: Co-ownership in Bulgaria

This paper analyzes how imperfections of property rights affect households’ allocation of assets using micro-survey data from Bulgaria. Co-ownership of assets is widespread in many countries due to inheritance. Central and Eastern Europe offers an interesting natural experiment to assess the effects of this type of property rights imperfection because of the asset restitution process in the 1990s. In Bulgaria, where co-ownership is very prominent and land is strongly fragmented, the land reform and inheritance legislation allows identifying the impact of co-ownership by taking advantage of a discontinuity created by a minimum plot size law. We find that land in co-ownership is more likely to be used by less efficient farm organizations or to be left abandoned, and that it is related to significant welfare losses. The paper hence provides evidence of sub-optimal land allocation following a privatization that established formal but imperfect property rights.     

Endogenous protection of R&D investments

Abstract .  We examine firms' incentives to protect their non-cooperative R&D investments from spilling over to competitors. We show that, contrary to findings in most of the literature, the lack of full appropriability can lead to an increase in R&D investments. Consequently, as long as the R&D spillovers are not too strong, firms decide to let their R&D knowledge flow. Since, as we show, welfare is higher when R&D spillovers are present, it follows that public policies that promote the dissemination of technological knowledge could be welfare-enhancing.     

Managerial incentives, CEO characteristics and corporate innovation in China’s private sector

We use a unique World Bank survey of 1088 private manufacturing firms from 18 Chinese cities over the period 2000-2002 to empirically examine the roles of managerial incentives and CEO characteristics in a firm’s innovation activities. We look at both innovation effort (R&D intensity) and innovation performance measures such as new product sales. We obtain the following main results: (1) the presence of CEO incentive schemes increases both corporate innovation effort and innovation performance; (2) sales-based performance measures in the incentive scheme, as compared with profit-based performance measure, are more conducive to firm innovation; and (3) CEO education level, professional background and political connection are positively associated with firm’s innovation efforts. The main results are robust to endogeneity tests with instrumental variables. We also discuss some important policy implications.     

Technology clubs, R&D and growth patterns: Evidence from EU manufacturing

This paper investigates the forces driving output change in a panel of EU manufacturing industries. A flexible modeling strategy is adopted that accounts for: (i) inefficient use of resources and (ii) differences in the production technology across industries. With our model we are able to identify technical, efficiency, and input growth for endogenously determined technology clubs. Technology club membership is modeled as a function of R&D intensity. This framework allows us to explore the components of output growth in each club, technology spillovers and catch-up issues across industries and countries.     

International R&D spillovers and institutions

The empirical analysis in “International R&D Spillovers” [Coe, D., Helpman, E., 1995. International R&D Spillovers. European Economic Review, 39, 859-887] is first revisited on an expanded data set that we have constructed for the purpose of this study. The new estimates confirm the key results reported in Coe and Helpman about the impact of domestic and foreign R&D capital stocks on TFP. In addition, we show that domestic and foreign R&D capital stocks have measurable impacts on TFP even after controlling for the impact of human capital. Furthermore, we extend the analysis to include institutional variables. Our results suggest that institutional differences are important determinants of TFP and that they impact the degree of R&D spillovers. Countries where the ease of doing business and the quality of tertiary education systems are relatively high tend to benefit more from their own R&D efforts, from international R&D spillovers, and from human capital formation. Strong patent protection is associated with higher levels of total factor productivity, higher returns to domestic R&D, and larger international R&D spillovers. Finally, countries whose legal systems are based on French and, to a lesser extent, Scandinavian law benefit less from their own and foreign R&D capital than countries whose legal origins are based on English or German law.     

The human capital consequences of civil war: Evidence from Guatemala

We combine data from the 2002 National Population Census and the distribution of the number of human rights violations and victims across 22 departments to examine how Guatemala's 36-year-long civil war affected human capital accumulation. The year of birth and the department of birth jointly determine an individual's exposure during school age to three different periods of the civil war, namely the initial period (1960-1978), the worst period (1979-1984), and the final period (1985-1996). We find a strong negative impact of the civil war on the education of the two most disadvantaged groups, namely rural Mayan males and females. Among rural Mayan males, those who were school age during the three periods of the civil war in departments where more human rights violations were committed completed 0.27, 0.71, and 1.09 years less of schooling respectively whereas rural Mayan females exposed to the three periods of the war completed 0.12, 0.47, and 1.17 years less of schooling respectively. Given an average of 4.66 and 3.83 years of schooling for males and females, these represent declines of 6, 15, and 23% for males and 3, 12, and 30% for females. Our results are robust to the inclusion of indicators for department of residence, year of birth, and controls for different trends in education and human development in war-affected and peaceful departments of Guatemala and suggest that the country's civil war may have deepened gender, regional, sectoral, and ethnic disparities in schooling.     

On the transaction values of land use rights in rural China

Land Use Rights (LURs) in China affect farmers’ productivity through investment incentives and the way land is allocated across households. LURs have implication and trade-offs between equity and growth. This paper examines how Chinese farmers might respond if the Chinese government made it legal for farmers to buy or sell LURs. Livelihood choices, labor substitution, market infrastructure, a lack of property right protections, entrepreneurship, bureaucracy, and political will are all influential factors that will determine whether such a program would work. The purpose of this paper is to examine the economics of transaction in LURs, estimate the value at which LURs could transact in equilibrium, and to analyze factors that would affect these price changes. We evaluate farmer’s intention to buy and sell LURs and how much they are willing to pay and receive for LURs.     

AIDS mortality and its effect on the labor market: Evidence from South Africa

This paper investigates how HIV/AIDS has impacted the labor market in South Africa, focusing on its effect on wages and employment. This is done by matching individual level data with group specific cumulative AIDS mortality rates. Exploiting the panel nature of the data, I remove individuals whose productivity is most likely impacted by HIV/AIDS, and find evidence that cumulative AIDS mortality has led to reductions in wages of between 3 and 6% for the African population group (Black South Africans). Furthermore, I also find evidence that the epidemic has lowered employment in South Africa. This result is concentrated among those with the lowest levels of education and employment. Although not large in magnitude, these effects are widespread across a significant portion of the population, contributing to a substantial loss of income throughout the South African economy.     

SCIENCE-BASED R&D IN SCHUMPETERIAN GROWTH

Firm success is often associated with the development of better products. Private firms undertake applied R&D seeking market advantage, by capitalizing on the freely accessible results of basic research. But unpatentable basic research often fails to address applied R&D open problems. What is the role of the incentives in improving the innovative performance of an economy by matching partially motivated public researchers to their mission? Sometimes government-funded research projects are mission-directed, and yet in many cases the public sector academics indulge in carrier-driven research. An innovation system where, as in the United States, basic research is also driven by patents implicitly sets an ex-post incentive to the researchers guided by invisible hand. For a public innovation system – like the European one – designing an incentive scheme to motivate public researchers is of key importance for fostering the performance of the economic system. This paper extends the Schumpeterian multisector growth model with vertical innovation by highlighting a link between the degree of 'targetness' of public research and aggregate innovation. A positive effect of social capital is also proved.     

Antidumping protection and R&D competition

Abstract.  In recent years antidumping protection has spread throughout the world. Evidence shows that antidumping often targets R&D‐intensive sectors, raising a concern that it may adversely affect worldwide investments in R&D. We investigate this issue in a model of reciprocal dumping extended to a two‐stage game, in which two firms first choose R&D levels and then compete in prices. We find that, when a single government institutes antidumping law, the protected firm decreases investment in R&D, while the constrained firm invests more. When both governments engage in antidumping actions, both firms invest more in R&D than under free trade. JEL classification: F12, F13     

Wars and Child Health: Evidence from the Eritrean-Ethiopian Conflict

Conflict between and within countries can have lasting health and economic consequences, but identifying such effects can be empirically challenging. This paper uses household survey data from Eritrea to estimate the effect of exposure to the 1998-2000 Eritrea-Ethiopia war on children's health. The identification strategy exploits exogenous variation in the conflict's geographic extent and timing and the exposure of different birth cohorts to the fighting. The unique survey data include details on each household's migration history, which allows us to measure a child's geographic location during the war and without which war exposure would be incorrectly classified. War-exposed children have lower height-for-age Z-scores, with similar effects for children born before or during the war. Both boys and girls who are born during the war experience negative impacts due to conflict. Effects are robust to including region-specific time trends, alternative conflict exposure measures, and mother fixed effects.     

Consumption risk, technology adoption and poverty traps: Evidence from Ethiopia

Much has been written on the determinants of technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well documented: the differential ability of households to take on risky production technologies for fear of the welfare consequences if shocks result in poor harvests. Building on an explicit model, this is explored in panel data from Ethiopia. Historical rainfall distributions are used to identify consumption risk. Controlling for unobserved household and time-varying village characteristics, it emerges that not just ex ante credit constraints, but also the possibly low consumption outcomes when harvests fail, discourage the application of fertilizer. The lack of insurance or alternative means of keeping consumption smooth leaves some trapped in low return, lower risk agriculture, one of the mechanisms through which poverty perpetuates itself in agrarian settings.     

Anti-competitive conduct, in-house R&D, and growth

Incumbent firms have two basic possibilities to improve their competitive position in the product market: Investment in R&D and the creation of entry barriers to the disadvantage of potential rivals, e.g. through lobbying activities, campaign contributions, bribes or the adoption of incompatible technologies. This paper proposes a simple oligopoly model which raises the possibility that such anti-competitive conduct and R&D investment are complementary activities for incumbents. Consequently, an institutional framework or technological possibilities which encourage anti-competitive conduct, although impeding entry of potential rivals and accentuating standard oligopoly distortions, may foster R&D-based growth and welfare. However, this outcome is less likely if entrants exert technological spillover effects, e.g. through foreign direct investment. Stronger protection of intellectual property rights, although triggering anti-competitive conduct and thereby impeding market entry as well, is more likely to foster economic growth.     

Crime and growth convergence: Evidence from Mexico

Scholars have often argued that crime hinders growth, but the empirical literature assessing such an effect is scarce. By exploiting cross-municipal income and crime data for Mexico, in this study we find evidence indicating that drug-related crime indeed deters growth.     

Firm growth and R&D: Evidence from the Portuguese manufacturing industry

This work studies the effects of R&D activities and investment, both physical and R&D, on the growth of firms by considering a dynamic firm growth model with serial correlation. The main hypotheses maintain that firms with a strong commitment to R&D have a higher growth rate, and investment has a positive effect on firm growth. We investigate such relations with reference to an unbalanced panel data set of Portuguese manufacturing firms over the period of 1990 to 2001. We find that a systematic tendency for smaller firms to grow more quickly is the main reason why firm growth is not entirely stochastic.     

Moral hazard and Marshallian inefficiency: Evidence from Tunisia

We formalize the link between optimal cost-sharing contracts and the production technology in the presence of moral hazard by appealing to several well-known results from duality theory. Building on intuitions from the interlinkage literature, we show that optimal contractual structure is determined by the (i) substitution possibilities that exist between different observable factor inputs, as well as (ii) between these inputs and unobservable effort. We endogenize contractual choice using landlord characteristics as instruments, exploiting the fact that, in our dataset, landlords interact with several tenants and vice versa. The approach is applied to an unbalanced plot-level panel of cost-sharing contracts in a Tunisian village, using a translog representation of the restricted profit function. Contractual terms are found to be a significant determinant of input use and therefore lead to Marshallian inefficiency, while the optimality of the underlying contractual structure is rejected.     

Tenure security and land-related investment: Evidence from Ethiopia

We use a large data set from Ethiopia that differentiates tenure security and transferability to explore determinants of different types of land-related investment and its possible impact on productivity. While we find some support for endogeneity of investment in trees, this is not the case for terraces. Transfer rights are unambiguously investment-enhancing. The large productivity effect of terracing implies that, even where households undertake investments to increase their tenure security, the level of such investment may be below the social optimum. In Ethiopia, government action to increase tenure security and transferability of land rights can significantly enhance rural investment and productivity.     

Trade policy mix: IPR protection and R&D subsidies

Abstract .  This paper analyses strategic R&D policy under circumstances where intellectual property rights protection resulting from firms' R&D investment is not perfect. By examining policy choices wherein a government chooses both R&D subsidies and IPR protection levels simultaneously, we show that it is optimal for a government to adopt sufficiently weak IPR protection and to subsidize R&D investments of domestic firms. Inducing R&D investment of foreign rival firms will increase the profits of domestic firms.     

The struggle to survive in the R&D sector: Implications for innovation and growth

By allowing for investment activities by research and development (R&D) firms to prevent product obsolescence, we show that if legal patent protection is too strong, a higher R&D subsidy rate delivers insufficient investments for survival in the R&D sector, depressing innovation and growth in the long run.
