This paper investigates the behaviour of bodies or organizations, operating in a stochastic environment, where there is a delegated decision maker.  A crucial decision is when to delegate to another decision maker.  The problem may be intrapersonal, as occurs when there are endogenously...

A convergence model with wealth accumulation subject to i.i.d. random shocks is examined. The transfer function shows what k_{t+1} - wealth at t+1 - would be, given k_t, with no shock: It has a positive slope, but its concavity/convexity is indeterminate. The stationary distribution of wealth...

A convergence model in which wealth accumulation is subject to i.i.d. random shocks is examined. The accumulation functions shows what k_{t+1} - wealth at t+1 - would be given k_t and with no shock. It has a positive slope, but its concavity or convexity is indeterminate. The focus is the...

Consistent with the theory of real options, it is argued that the value of the Employment Guarantee Scheme (EGS) in the Indian state of Maharashtra and its impact on workers` behaviour do not depend so much on its income supplementation as on enlargement of opportunities in an uncertain...

We model the interplay between a government's performance, its expected lifetime, and the confidence it enjoys. Here, "confidence" can be broadly interpreted as the government's popularity, the size of its parliamentary majority, its reserve of talent, or other factors. Confidence evolves in...

An online platform makes a profit by auctioning an advertising slot that appears whenever a consumer visits its website.  Several firms compete in the auction, and consumers differ in their preferences.  Prior to the auction, the platform gathers data which is statistically correlated with...

We present a general Cournot model in which each firm may sell multiple quality-differentiated products. We use an upgrades approach, working not with the actual products, but instead with upgrades from one quality to the next. The properties of single-product Cournot models carry over to the...

We develop a bidimensional matching model under transferable utility, where individuals are characterized by a continuous trait (e.g., socioeconomic status) and a binary attribute (e.g., smoking status).  The model is "truly multidimensional", in the sense that the impact of the traits cannot...

Children are increasingly treated as active members in the household.  However, their preferences over consumption and leisure are rarely modelled.  This paper considers heterogeneity in siblings' preferences over leisure and consumption and builds a theoretical and empirical model for...

We report the short-term results from a randomized evaluation of a mobile phone literacy and numeracy program (Project ABC) in Niger, in which adult literacy students learned how to use mobile phones as part of a literacy and numeracy class.  Students in ABC villages showed substantial gains in...
