Inside the Black Box: Partnerships in Rio de Janeiro, 1870-1891

We use newly-constructed individual-level data on partnership contracts in late nineteenth century Rio de Janeiro to examine differences between limited and unlimited liability firms and partners, and to assess the impact of a major institutional reform that facilitated the formation of joint stock companies on the terms of partnership contracts. Contrary to expectation, we find that most unlimited partners contributed capital and received profit shares, and most non-managing limited partners received salaries. Limited partners contributed more capital and received lower salaries and profit shares than their unlimited partners; unlimited partners in limited firms received more favorable terms than those in unlimited firms. Finally, we find suggestive evidence that the reforms reduced the extent of income smoothing for the limited partner and increased the average quality of unlimited liability partners in limited liability firms. These findings highlight the role of incentives and the desire for income smoothing in shaping contract terms.Partnerships, Brazil

Bednets, Information and Malaria in Orissa

This paper studies the identification and estimation of a basic model of technology adoption using specifcally collected information on subjective beliefs and expectations to identify key model parameters. We discuss identifcation with both non-parametrically and parametrically specified utility as well as parametric and semi-parametric specifcations for unobserved heterogeneity. We propose parametric and semi-parametric estimation methods to recover underlying preferences and use the model to study the adoption of Insecticide Treated Nets (ITNs) among poor households in rural India. We carry out counterfactual exercises to examine the effects of price and belief changes on net ownership decisions. The results suggest that purchase decisions are relatively insensitive to changes from current prices and beliefs. The method proposed here should have applicability to other discrete choice settings with non-linear indices.Malaria, Expectations, Bednets, Identication, Median Restrictions

Does Management Matter? Evidence from India

A long-standing question in social science is to what extent differences in management cause differences in firm performance. To investigate this we ran a management field experiment on large Indian textile firms. We provided free consulting on modern management practices to a randomly chosen set of treatment plants and compared their performance to the control plants. We find that adopting these management practices had three main effects. First, it raised average productivity by 11% through improved quality and efficiency and reduced inventory. Second, it increased decentralization of decision making, as better information flow enabled owners to delegate more decisions to middle managers. Third, it increased the use of computers, necessitated by the data collection and analysis involved in modern management. Since these practices were profitable this raises the question of why firms had not adopted these before. Our results suggest that informational barriers were a primary factor in explaining this lack of adoption. Modern management is a technology that diffuses slowly between firms, with many Indian firms initially unaware of its existence or impact. Since competition was limited by constraints on firm entry and growth, badly managed firms were not rapidly driven from the market.management, organization, IT, productivity and India

Credit Constraints and the Measurement of Time Preferences

Incentivized experiments are commonly used to estimate marginal rates of intertemporal substitution (MRS) in the lab and in the field in order to make inferences about individual time preferences. This paper considers an integrated model of behavior in which individuals are subject to financial shocks and credit constraints, and take those into account when making experimental choices. The model shows that measured MRS depends on the individual’s effective interest rate which is equal to the relative marginal utility of current and future consumption. Experimental responses should therefore be correlated with other variables that describe the subject’s financial situation, like savings and shocks to income and consumption. We test the model using a new a panel data set from Mali and find evidence for such effects. Our results imply that the relationship between experimentally elicited MRS and time preferences is not straightforward. However, measured MRS can be useful in determining the importance of different types of financial shocks to the household

Identification and Estimation of Regression Models with Misclassification

This paper studies the problem of identification and estimation in nonparametric regression models with a misclassified binary regressor where the measurement error may be correlated with the regressors. We show that the regression function is nonparametrically identified in the presence of an additional random variable that is correlated with the unobserved true underlying variable but unrelated to the measurement error. Identification for semiparametric and parametric regression functions follows straightforwardly from the basic identification result. We propose a kernel estimator based on the identification strategy, derive its large sample properties, and discuss alternative estimation procedures. We also propose a test for misclassification in the model based on an exclusion restriction that is straightforward to implement. Copyright The Econometric Society 2006.

Time Inconsistency, Expectations and Technology Adoption: The case of Insecticide Treated Nets

Economists have recently argued that time inconsistency may play a central role in explaining intertemporal behavior, particularly among poor households. However, time-preference parameters are typically not identified in standard dynamic choice models and little is known about the fraction of inconsistent agents in the population. We formulate a dynamic discrete choice model in an unobservedly heterogeneous population of possibly time-inconsistent agents motivated by specifically collected information combined with a field intervention in rural India. We identify and estimate all time-preference parameters as well as the population fractions of time-consistent and “naïve ” and “sophisticated ” timeinconsistent agents. We estimate that time-inconsistent agents account for more than half of the population and that “sophisticated ” inconsistent agents are considerably more present-biased than their “naïve ” counterparts. We also examine whether there are other differences across types (e.g. in risk and cost preferences) and find that these differences are small relative to the differences in time preferences.
