Using a global panel on research and development (R&D) expenditures, this paper documents that on average poor countries do far less R&D than rich as a share of GDP. This is arguably counter intuitive since the gains from doing the R&D required for technological catch up are thought to be very...

An abundance of natural resources is both an opportunity and a challenge for developing countries. Several resource-rich, low-income countries receive amounts of foreign aid that are similar to or larger than their actual or potential revenues from natural resources. In such countries, the...

The need for land-related investment to ensure sustainable land management and increase productivity of land use is widely recognized. However, there is little rigorous evidence on the effects of property rights for increasing agricultural productivity and contributing toward poverty reduction...

The author uses date from the 1992-93 and 1997-98 Vietnam Living Standards Survey (VLSS) to describe patterns of money transfers between households. Rapid economic growth during the 1990s did little to diminish the importance of private transfers in Vietnam. Private transfers are large and...

Under communal farm production, there was little incentive to work hard: the communal system guaranteed a livelihood, and there were few private gains from additional efforts. The reform that introduced the household responsibility system in China in the early 1980s sharpened individual work...

The authors 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 they find some support for endogeneity of investment in trees, this is not...

In a context of rapid urbanization and energy transition, massive investments will be required to develop efficient public transport networks. Capturing the increase in land value caused by transport infrastructure (for example, through a betterment tax) appears a promising way to finance public...

The authors test whether poor households use cash transfers to invest in income generating activities that they otherwise would not have been able to do. Using data from a controlled randomized experiment, they find that transfers from the Oportunidades program to households in rural Mexico...

When contracts are incomplete, relationship-specific investments may be underprovided due to the threat of opportunistic expropriation or holdup. The authors find evidence of such underinvestment on tenanted land in rural Pakistan. Using data from households cultivating multiple plots under...

Although sharecropping has long fascinated economists, the determinants of this contractual form are still poorly understood and the debate over the extent of moral hazard is far from settled. The authors address both issues by emphasizing the role of landlord supervision. When tenant effort is...
