We characterize three classes of demand systems, all of which are defined non-parametrically: homothetic demand systems with a single aggregator (HSA), those with direct implicit additivity (HDIA), and those with indirect implicit additivity (HIIA). In HSA, all the cross-price effects are captured by one price aggregator, while in HDIA and in HIIA, they are captured by two price aggregators. Each of these three classes contains CES as a special case. Yet, they are pairwise disjoint with the sole exception of CES. Thus, these classes of homothetic demand systems offer us three alternative ways of departing from CES.

В данной работе исследуются панельные данные межрегиональной миграции в России 1995-2010 годах. Результаты исследования показали, что барьеры миграции, сдерживающие миграционные процессы в 1990-е, практически исчезли к 2010 году. В 1990-е года большинство российских регионов находилось в ловушках бедности: потенциальные мигранты хотели покинуть регион проживания, но не имели возможности этого сделать. В 2000-х годах, в частности с 2005 года, эти барьеры исчезли. Всеобщий экономический рост и развитие финансовой системы позволило российским регионам выйти из ловушек бедности. Это привело к конвергенции регионов по показателям рынка труда и среднедушевым доходам. Межрегиональные различия в заработных платах, среднедушевых доходах и уровнях безработицы существенно снизились до уровня Европейских стран.

We propose and characterize parametric families of homothetic demand systems, which feature a constant pass-through rate that is common across otherwise heterogenous monopolistically competitive firms. These parametric families offer natural, flexible, and yet tractable extensions of CES. In the case of complete pass-through, the markup rate is constant, as in CES, yet it can be heterogenous across firms, unlike in CES. In the case of incomplete pass-thorough, the price of each firm is log-linear in its marginal cost and its choke price with the common coefficients across firms. Tougher competition, captured by a lower “average price,” reduces the prices of all firms at a uniform rate, and hence without affecting their relative prices. Yet, it causes a disproportionately larger decline in the revenue and the profit among firms with lower markup rates.

In existing models of endogenous innovation cycles, market size alters the amplitude of fluctuations without changing the nature of fluctuations. This is due to the ubiquitous assumption of CES homothetic demand system, implying that monopolistically competitive firms sell their products at an exogenous markup rate in spite of the empirical evidence for the procompetitive effect of entry and market size. We extend a model of endogenous innovation cycles to allow for the procompetitive effect, using a more general homothetic demand system, which contains both CES and translog as special cases. We show that a larger market size and/or a smaller innovation cost, which causes the markup rate to decline through the procompetitive effect, has destabilizing effects on the dynamics of innovation.

 Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this paper, we investigate how social norms affect individual effort, aggregate effort, and welfare. While individual productivity always positively affects own effort and utility, we show that taste for conformity has an ambiguous effect on individual outcomes and depends on whether an individual is above or below her own social norm. Equilibria are usually inefficient and, to restore the first best, the planner subsidizes (taxes) agents whose neighbors make efforts above (below) the social norms in equilibrium. Thus, provision of more subsidies to more central agents is not necessarily efficient.

The Dixit-Stiglitz model of monopolistic competition with symmetric CES demand system with gross substitutes is widely used as a building block across many applied general equilibrium fields. Two of its remarkable features are the invariance of the markup rate and the optimality of the freeentry equilibrium. Of course, neither of these two features is robust. Departure from CES makes entry either procompetitive or anticompetitive (i.e., the markup rate either goes down or goes up as more firms enter). Departure from CES also makes entry either excessive or insufficient. But how is the condition for procompetitive vs. anticompetitive entry related to that for excessive vs. insufficient entry? To investigate this question, we extend the Dixit-Stiglitz monopolistic competition model to three classes of homothetic demand systems, which are mutually exclusive except that each of them contains CES as a knife-edge case. In all three classes, we show, among others, that entry is excessive (insufficient) when it is globally procompetitive (anticompetitive) and that, in the presence of the choke price, entry is procompetitive and excessive at least for a sufficiently large market size.
