Trade costs, resource reallocation and productivity in developing countries

An increasing body of evidence indicates that an important share of aggregate productivity growth, in both developed and developing countries, arises from the reallocation of resources across plants of different productivity levels. New trade models with heterogeneous firms (Bernard et al., 2003; Melitz, 2003) suggest that international trade plays an important role in this reallocative process. Focusing on a developing country, Chile, we use explicit measures of trade costs to explore the existence of the channels suggested by these new trade models. We provide new key findings for developing countries: first, trade costs affect the reallocative process by protecting inefficient producers, lowering their likelihood to exit, and also by limiting the expansion of efficient plants, lowering their likelihood to export. Second, the reallocative impacts of trade arise not only from tariff barriers but also from transport costs.Trade costs, productivity, resource reallocation

Integration, resource reallocation and productivity: the cases of Brazil and Chile

Most microeconometric studies available for LAC have focused on measuring the direct impact of trade on plant productivity leaving aside other effects that arise through the market selection process. Additionally, most studies have focused on tariff barriers as the only obstacle to international trade and integration. In this paper we use data from Brazil and Chile to analyze how trade affects aggregate productivity through the process of resource reallocation and to explore not only the role of tariffs but also the role of transport costs. We find that trade costs affect the reallocative process by protecting inefficient producers, lowering their likelihood to exit, and also by limiting the expansion of efficient plants, lowering their likelihood to export. We also find that the reallocative impacts of trade come not only from tariff barriers but also from transport costs.Tariff barriers, transport costs, productivity, resource reallocation

Ising-Kac models near criticality

The present thesis consists in an investigation around the result shown by H. Weber and J.C. Mourrat in [MW17a], where the authors proved that the fluctuation of an Ising models with Kac interaction under a Glauber-type dynamic on a periodic two-dimensional discrete torus near criticality converge to the solution of the Stochastic Quantization Equation Φ 4/2. In Chapter 2, starting from a conjecture in [SW16], we show the robustness of the method proving the convergence in law of the fluctuation field for a general class of ferromagnetic spin models with Kac interaction undergoing a Glauber dynamic near critical temperature. We show that the limiting law solves an SPDE that depends heavily on the state space of the spin system and, as a consequence of our method, we construct a spin system whose dynamical fluctuation field converges to Φ 2n/2. In Chapter 3 we apply an idea by H. Weber and P. Tsatsoulis employed in [TW16], to show tightness for the sequence of magnetization fluctuation fields of the Ising-Kac model on a periodic two-dimensional discrete torus near criticality and characterise the law of the limit as the Φ 4/2 measure on the torus. This result is not an immediate consequence of [MW17a]. In Chapter 4 we study the fluctuations of the magnetization field of the Ising-Kac model under the Kawasaki dynamic at criticality in a one dimensional discrete torus, and we provide some evidence towards the convergence in law to the solution to the Stochastic Cahn-Hilliard equation

When does Innovation Matter for Exporting?

A growing number of studies that look at the relationship between innovation and exports find that more innovation tends to allow firms to export more. But very little is known about the heterogeneous impacts of innovation on exports. Since innovation is not a costless activity, it is important to know the specific situations in which a firm most likely needs to innovate to raise its exports. Using data from Chile, we combine information on innovation activities at the firm level with a rich dataset on exports at the transaction level. We find that the firms that engage in innovation tend to export more than other firms because they are able to sell goods and target markets that reward innovation. We show that the goods and markets in which innovative exporters outperform non-innovative exporters are those where innovation can lead to substantial differences in terms of quality. Innovative firms do not have an edge in exporting goods and in targeting markets that do not reward innovation. In particular, innovative firms do not outperform non-innovative firms when exporting goods and penetrating markets in which differentiation in terms of quality is not possible or not relevant
