We propose an evolutionary equation and develop an asymptotic theory that generalize results obtained in Polterovich, Khenkin, 1988. It is shown that, as a result of interaction between innovation and imitation, the shape of the efficiency distribution curve of technologies eventually...

The paper is devoted to investigation of a number of difference-differential equations, among them the following one plays the central role: dFn/dt=φ(Fn)(Fn-1 - Fn) (*) where, for every t, {Fn(t), n = 0, 1, 2, ...} is a probability distribution function, and φ is a positive function on [0, 1]....

This paper studies the evolution of the distribution of firms in the ferrous metals industry by efficiency levels. The proposed model takes into account interaction of processes of creation and adoption of technologies and depreciation of assets. It is shown that the model approximates real data...

We propose a difference-differential equation that reflects interactions between innovation and imitation processes to describe the evolution of the distribution curve of firms by efficiency levels. An explicit solution of this equation is obtained for arbitrary finite initial conditions. It is...

The concepts of absorptive capacity and innovative capability have been introduced to describe abilities of a country to imitate and, accordingly, to create more advanced technologies. In this paper we suggest new indicators of these two abilities. To calculate them, we develop an endogenous...

In this paper, we incorporate a price search decision into a life cycle model and differentiate consumption from expenditure. Consumers with low wealth and bad income shocks search more for cheaper prices and pay less, which makes their consumption higher than in a model without search option. A...

There is substantial heterogeneity in the gender gaps in unemployment across OECD countries. We incorporate labor market conditions, moral hazard and home production into a quantitative model of unemployment. The model can explain most of the gender gaps in unemployment across the OECD...

In this paper, we study the interaction between self insurance and public insurance. In particular, we provide evidence on the relationship between unemployment insurance benefits and home production using the American Time Use Survey (ATUS) and the state-level unemployment insurance data of...

In this paper, we incorporate home production into a quantitative model of unemployment and show that realistic levels of home production have a significant impact on the optimal unemployment insurance rate. Motivated by recently documented empirical facts, we augment an incomplete markets model...
