Rental markets,gender, and land certificates: Evidence from Vietnam

In developing countries, a significant share of land transactions occurs among closely related parties and often does not entail any specific compensation (in-kind or monetary). Despite the prevalence of these non-market or informal transactions, the literature has paid little attention to the determinants and consequences of these exchanges. In this paper we shed light on the role land use certificates play on the agreed compensation of rental agreements when landlords, particularly those with weaker ex-ante tenure security (i.e. women), rent out land to their relatives in Viet Nam. We find that female-headed households who lease their plots to relatives are less likely to receive any type of payment, unless they possess a title for the plot they leased. A regional decomposition of our results shows that this effect is more predominant in the Northern regions.     

Bargaining power,decision making,and biofortification: The role of gender in adoption of orange sweet potato in Uganda

We examine the role of gender dimensions of intrahousehold bargaining power and decision making in the adoption and diffusion of orange sweet potato (OSP), a biofortified crop being promoted to increase dietary intakes of vitamin A in Uganda. We use patterns of ownership and control of land and other assets by married men and women to create gender-disaggregated indicators of bargaining power, allowing for joint and sole ownership and control of land and assets. Using data from an experimental evaluation of a project promoting OSP adoption, we find that the probability of adopting OSP is not affected by the exclusive or joint control of assets by women at the household level. However, within households, parcels of land under joint control, in which the woman has primary control over decision making, are significantly more likely to contain OSP. Women who control a higher share of household nonland resources are more likely to share OPS vines, showing that women use greater bargaining power to facilitate diffusion of this health-promoting technology. We do not find any impact of women’s bargaining power on children’s dietary intakes of Vitamin A, possibly because husbands and wives have the same preferences regarding their children’s nutritional status. These results contribute to reshaping our understanding of household decision making to inform the design and implementation of agriculture-nutrition interventions.     

Housing,Wealth, Income and Consumption: China and Homeownership Heterogeneity

Impacts on consumer spending in urban China associated with housing value, housing equity, financial assets and household income are evaluated using longitudinal data from the China Family Panel Studies (CFPS) survey. Findings suggest that the housing wealth effect on household consumption in China is much larger than has been shown for developed economies. The larger impact is prospectively related to structural limits on investing which favor real estate ownership, along with the dominant position of housing in total household wealth. We also find that a household's consumption varies across housing tenure. Homeowners having joint ownership of property on average have the highest consumption propensity, while those having sole ownership of property consume the most in response to appreciation in housing wealth.     

Household portfolio choice before and after a house purchase

Using a unique administrative panel data from Denmark, this article documents the dynamic evolution of households' financial wealth, the equity market participation rate (extensive margin), and the conditional risky asset share of financial wealth (intensive margin) over a 7-year period around a house purchase. We find that households' equity market participation rate falls during the year of house purchase. Conditional on participation, the risky asset share of financial wealth follows a V-shape around the house purchase. It decreases and reaches the lowest point 1 year before a house purchase, but jumps up immediately after. This finding suggests that of the three channels identified in the literature that are related to the risky asset demand after a house purchase, the debt retirement channel and the diversification effect dominate the liquidity concern.     

Minimum Cash Wages,Tipped Restaurant Workers,and Poverty

This is the first study to examine the effect of increases in the tipped minimum cash wage—the wage employers must pay to tipped employees—on poverty. Using March Current Population Survey data (1988–2014), we find that tipped minimum cash wage increases are associated with declines in the risk of a tipped restaurant worker living in a poor family (elasticities around –0.2). However, we find little evidence of poverty‐alleviating effects when using the household rather than the family as the sharing unit. This result is consistent with evidence that a substantial share of tipped workers who live in a poor family live in a nonpoor household with persons unrelated by blood, marriage, or adoption who contribute to the household's income. Furthermore, we find that tipped minimum cash wage hikes are associated with increases in the risk of a younger, less‐educated individual living in a poor family or household. Adverse labor demand effects that redistribute income among low‐skilled individuals drive these results. We conclude that raising the tipped minimum cash wage is a poorly targeted policy to deliver income to poor restaurant workers.     

The price effects of greening vacant lots: How neighborhood attributes matter

We identify the effects of greening vacant lots on nearby housing prices and show how neighborhood attributes matter to these outcomes. Using data from a longstanding program in Philadelphia, we find that prices for houses within 1,000 feet of a greened vacant lot rise by about 4%, consistent with the literature, with the effect size increasing over time. Using the extensive data available in Philadelphia, we show how these effects vary by the attributes of the neighborhood in which they occur, with larger effects in areas with a high share of vacant land and higher-than-average median household incomes, with peak responses estimated at 19% and 15%, respectively. We demonstrate the importance of sample selection bias adjustment for identification of the effect of vacant lot greening.     

Innovation,R&D productivity,and global market share in the pharmaceutical industry

In this paper, we estimate two empirical models using a pooled, cross-section sample of international pharmaceutical firms for the period 1987 to 1989. The first model tests the relationship between R&D productivity and a vector of firm-specific characteristics. The second model tests the determinants of global market share. The empirical analysis reveals three findings. First, we find evidence that there are diminishing returns in the pharmaceutical R&D process. Second, we find that firm size has a positive effect on average R&D productivity and a positive impact on the marginal R&D productivity for plausible R&D staff sizes. And third, we find evidence that R&D productivity and the number of sales employees have a positive effect on the firm's global market share.The views presented in this paper reflect those of the authors and do not necessarily reflect the views of the U.S. International Trade Commission or any of its individual commissioners.

Conflict,food price shocks,and food insecurity: The experience of Afghan households

Using nationally-representative household survey data and confidential geo-coded data on violent incidents, we examine the relationship between conflict and food insecurity in Afghanistan. Spatial mappings of the raw data reveal large variations in levels of food insecurity and conflict across the country; surprisingly, high conflict provinces are not the most food insecure. Using a simple bivariate regression model of conflict (violent incidents and persons killed or injured) on food security (calorie intake and the real value of food consumed), we find mixed associations. But once we move to a multivariate framework, accounting for household characteristics and key commodity prices, we find robust evidence that in Afghanistan levels of conflict and food security are negatively correlated. We also find that households in provinces with higher levels of conflict experience muted declines in food security due to staple food price increases relative tohouseholds in provinces with lower levels of conflict, perhaps because the former are more disconnected from markets. Gaining a better understanding of linkages between conflict and food insecurity and knowing their spatial distributions can serve to inform policymakers interested in targeting scarce resources to vulnerable populations, for example, through the placement of strategic grain reserves or targeted food assistance programs.     

Assessing household food insecurity experience in the context of deforestation in Cameroon

BackgroundIn forest areas, reconciling strategies to halt deforestation and concerns to improve sustainable food supply and access is a great challenge to development planners and forest managers. This paper gathered evidence on the relationship between deforestation and food insecurity. The study was executed in Cameroon’s forest areas which constitute 10% of the Congo basin forest - an area characterized by increasing deforestation and high levels of poverty and food insecurity (FIS). The objective was to understand the characteristics, prevalence and severity of household FIS as deforestation increases. The HFIAS 9-item questionnaire for measuring experience-based FIS was used for data collection and analysis.ResultsAt least one-third of households at all levels of deforestation were severely food insecure and more than half of the population suffered from moderate to severe FIS. Most (97%) households reported experiencing food scarcity due to lack of resources. Households in the least deforested zone were better off than those in moderate and most deforested zones by most of the FIS indicators, while differences between the moderately and the most deforested zones were less distinct. Overall, considering a range of food insecurity indicators, households in the most deforested zone were the worst off.ConclusionHousehold FIS deteriorates with increasing deforestation and despite the generally favourable environmental conditions for food production, FIS was still high. This finding has major implications for development practitioners, land use planning, food security and conservation initiatives.     

Housing Tenure Transitions of Older Households: What is the Role of Child Proximity?

This study examines the role of proximity of children to their parents and recent moves of children within a proximate distance in housing tenure transitions of older households. This study is the first to investigate the interplay between health status of older households, moves of their children and a household's decision to make housing tenure transitions. In doing so, we rely on longitudinal household data from the Panel Study of Income Dynamics with residential location information at the census tract level. The results demonstrate that after controlling for the financial and demographic characteristics of children, living near children reduces the likelihood of making a housing tenure transition for older households, but that the impact of distance is not monotonic with respect to the degree of geographic distances. The results also demonstrate that if a child enters or moves closer to her or his parents’ home, it increases the probability that older households exit homeownership. Finally, we find no evidence that children's moves mitigate the likelihood that their older parents whose health deteriorates become renters.     

Once an outsider,always an outsider? CEO origin,strategic change,and firm performance

In this study, we examine how the relationship between the level of strategic change in the pattern of resource allocation and firm performance differs between firms led by outside CEOs and those led by inside CEOs. Based on longitudinal data on the tenure histories of 193 CEOs who left office between 1993 and 1998, we find that the level of strategic change has an inverted U‐shaped relationship with firm performance. As the level of change increases from slight to moderate, performance increases; as the level of change increases from moderate to great, performance declines. Further, we find that this inverted U‐shaped relationship differs between firms led by outside CEOs and those led by inside CEOs. That is, both the positive effect of strategic change on firm performance when the level of change is relatively low and the negative effect of strategic change on firm performance when the level of change is relatively high are more pronounced for outside CEOs than for inside CEOs. Supplementary analyses also suggest that this difference between outside and inside CEOs exists in later years but not in the early years of CEO tenure. Copyright © 2009 John Wiley & Sons, Ltd.     

Population density,migration, and the returns to human capital and land: Insights from Indonesia

Rapid population growth in many developing countries has raised concerns regarding food security and household welfare. To understand the consequences of population growth in a general equilibrium setting, we examine the dynamics of population density and its impacts on household outcomes using panel data from Indonesia, combined with district-level demographic data. Historically, Indonesia has adapted to land constraints through a mix of agricultural intensification, expansion of the land frontier, and non-farm diversification, with public policies playing a role in catalyzing all of these responses. In contemporary Indonesia we find that human capital determines the effect of increased population density on per capita household consumption expenditure. The effect of population density is positive if the average educational attainment is high (above junior high school), while it is negative otherwise. On the other hand, farmers with larger holdings maintain their advantage in farming regardless of population density. The paper concludes with some potential lessons for African countries from Indonesia’s more successful rural development experiences.     

The impact of intra-platform competition on broadband penetration

There has been an extensive debate about the role of broadband access regulation on market outcomes. This paper estimates the impact that the different modes of competition have had on broadband take-up to date, using a data set for EU27 countries. We find that ULL, which is one of main types of access-based competition in Europe, has had a positive impact on broadband take-up. However, the impact of ULL becomes smaller as its share increases. That is, ULL entry is less effective in areas where ULL take up is already high. Further, there is evidence of a crowding out effect between ULL and inter-platform competition. This means that ULL is less effective in enhancing broadband penetration in the areas where alternative networks already have a significant share of broadband lines.     

Rising food prices and undernourishment: A cross-country inquiry

Households’ welfare in developing countries has been hit by dramatic food prices increases which occurred between 2005 and 2008. In this paper, we adopt a partial equilibrium approach to analyze the short-time effects of a staple food price increase on nutritional attainments, as a measure of welfare. The analysis consists of first approximating complete food-demand systems and then performing household level micro-simulations. Instead of focusing on a single country profile, we provide a more complete snapshot by comparing the evidence through a cross-country assessment made possible by the use of nationally representative household surveys. Comparability is assured by the adoption of the same methodological choices in the treatment of the micro data. We find that food price spikes not only reduce the mean consumption of dietary energy, but also worsen the distribution of food calories, further deteriorating the nutritional status of populations. We also discovered that access to agricultural land plays a significant role in ensuring adequate nutritional attainments in rural areas, and surprisingly, even in urban areas.     

Market failures and the additionality effects of public support to private R&D: Theory and empirical implications

We extend the theoretical basis of the empirical literature on the effects of R&D subsidies by providing an estimable model of strategic interaction among subsidy applicants, and public and private sector R&D financiers. Our model incorporates fixed R&D cost and a cost of external finance. We derive the optimal support rule. At the intensive (extensive) margin the costs of external funding reduce (increase) the optimal subsidy rate. We also establish necessary and sufficient conditions for the existence of additionality. It turns out that additionality at the intensive margin is less likely with higher spillovers. Our results suggest that the relationship between additionality and welfare may not be straightforward.     

A Disaggregate Analysis of the Evolution of Job Tenure in Britain, 1975–1993

We use data on 200,000 individuals to investigate changes in job tenure. We look at the age–tenure profile for different birth cohorts of workers and find little change for men and an improvement for women. We estimate probability models for two cuts of the tenure distribution. We find that, controlling for a set of age, demographic, educational, industrial and occupational characteristics, the proportion of workers in short jobs and longer jobs has the same path as in the aggregate (unconditional) analysis. Allowing for the effect of all these characteristics to vary with time uncovers no evidence of secular change.     

Fixed-to-mobile substitution in the European Union

This paper analyzes substitution between access to fixed-line and mobile telephony in the European Union using cross-section panel data on households’ choices of telecommunications technologies in years 2005–2010. We estimate a structural model of household?s demand for access to: (i) fixed-line only; (ii) mobile only; and (iii) both fixed-line and mobile. We find that growing Internet usage increases the share of ‘fixed + mobile’ households, which suggests that households keep their fixed-line connection to access Internet. However, the spread of 3G and cable broadband access decreases the share of ‘fixed + mobile’ households and increases the share of ‘mobile only’ households. Hence, fixed-to-mobile substitution was slowed down by the spread of Internet but it may continue with the spread of mobile broadband. Furthermore, bundling of telecommunications services increases the share of ‘fixed + mobile’ households and decreases the shares of ‘mobile only’ and ‘fixed only’ households. Therefore, operators which can bundle fixed-line connection with Internet or mobile services may slow down fixed-to-mobile substitution.     

The impact of agricultural commercialisation on household welfare in rural Vietnam

Commercialisation by smallholder farmers has played a major role in agricultural development in many Asian countries, and while there are assumptions that this has led to welfare improvement, in fact there is relatively little evidence on this question. In this paper we use high quality panel data to examine the welfare impact of agricultural commercialisation in a leading Asian producer, Vietnam. We use the five-wave Vietnam Access to Resources Household Survey (VARHS) panel data set from 2008 to 16, three measures of household welfare and create commercialisation indexes in relation to all crops and to rice specifically. We find a significant positive relationship of commercialisation with household asset accumulation, but a negative association with consumption expenditure.     

Knowledge worth having in ‘excess’: The value of tacit and firm‐specific human resource slack

Whether holding resources in excess of what is needed to sustain routine operations (i.e., having slack) increases or decreases firm performance is a question of ongoing interest to management scholars. We contribute to existing theory by arguing that human resource slack generally decreases a firm's performance but that holding excess numbers of employees who possess important tacit knowledge that is specific to firms may benefit the firm. We find that the value of these excess resources increases as firms face competitive pressures and decreases when firms' operational choices facilitate the standardization of workflows. We obtain initial empirical evidence for our predictions by testing them on a novel dataset comprising six years of data for 4,070 manufacturing plants in Mexico.
