Игорь Быкадоров, Сергей Коковин, Евгений Желободько. "Investments in productivity and quality under monopolistic competition".
We study impact of market size on endogenous productivity in a monopolistic competition model that allows for general (unspecied) utility and cost functions. A producer can invest in decreasing marginal cost or in increasing quality, whereas free entry drives prots to zero. It turns out that equilibrium investments increase with the market size if and only if utility shows decreasing elasticity of substitution, which is demand elasticity. We find conditions for social (non-)optimality of the market outcome. The same model is applied to investments in quality and show similar comparative statics and optimality. Extensions are outlined, including trade and heterogeneous firms.
Сергей Кичко. "Two-factor trade model with monopolistic competition".
We depelop a two-factor trade model with monopolistic competition, a variable elasticity of substitution and trade cost. We show that the country endowed with more capital is a net exporter of manufactured good and its capital price is smaller. The relative GDP share of the capital-endowed country is smaller than its relative share in capital. Last, dumping or reverse dumping may aim depending on consumers' altitude towards variety love and countries relative capital endowment.
Татьяна Михайлова. "Gulag, WWII and the long-run patterns of Soviet city growth".
This paper analyzes the geographical patterns of city growth in the Soviet Union and the Russian Federation in connection with Stalinist policies of 1930s-1950s and the events of WWII. Using a unique data set on the locations of Gulag camps and the evacuation of industrial enterprizes during WWII, I match camps and evacuated enterprizes to the nearest urban settlements. Presence of a Gulag labor camp nearby is a strong predictor of future population growth in Soviet cities. Cities where camps were located grow significantly faster than the average. WWII events (fighting on the front, evacuations) also affect local population growth, but their impact diminishes with time and disappears after 20-25 years. In contrast, Gulag camps have a long-lasting (in some cases permanent) effect on the city size.
