We examine a theory of competitive innovation in which new ideas are introduced only when diminishing returns to the use of existing ideas sets in. After an idea is introduced, the knowledge capital associated with that idea expands, and its value falls. Once the value falls far enough, it becomes...

This paper proposes a theory of rational bubbles in an economy with finite trading opportunities. Bubbles arise because agents are never sure to be last in the market sequence. This theory is used to design an experimental setting in which bubbles can be made rational or irrational by varying one...

The size properties of a two-stage test in a panel data model are investigated where in the first stage a Hausman (1978) specification test is used as a pretest of the random effects specification and in the second stage, a simple hypothesis about a component of the parameter vector is tested,...

We present a new non-parametric estimator of the conditional density of the kernel type. It is based on an efficient transformation of the data by quantile transform. By use of the copula representation, it turns out to have a remarkable product form.We study its asymptotic properties and compare...

I consider a dynamic model of competition between two proprietary networks. Consumers die and are replaced with a constant hazard rate; and firms compete for new consumers to join their network by offering network entry prices. I derive a series of results pertaining to: (a) existence and...

This paper assesses the long-run optimal level of public debt in a non Ricardian framework with aggregate fluctuations. Households are subject to aggregate and idiosyncratic risk, face borrowing constraints and the incompleteness of markets prevents them from perfectly insuring against risk. We...

We estimate the role of benefits and peer effects in technology Adoption using data from randomized distribution of menstrual cups in Nepal. Using individual randomization, we estimate causal effects of peer exposure on adoption; using differences in potential returns we estimate effects of...

We present a test of fit for the hypothesis that a time series comes form an AR(p) process, specially sensitive to alternative models AR(p+1), or ARMA(p,1). The testing procedure can be viewed as a particular example of a more general inferential procedure based on the study of certain random...

We use new data on entries and exits of US daily newspapers from 1869 to 2004 to estimate effects on political participation, party vote shares, and electoral competitiveness. Our identification strategy exploits the precise timing of these events and allows for the possibility of confounding...
