Although this is well understood theoretically, it is unclear how large the welfare distortions are in the aggregate economy. Do they matter quantitatively? To answer this question, we develop a multisector monopolistic competition model with endogenous firm entry and selection, productivity, and markups. Using French and UK data, we quantify the gap between the equilibrium and optimal allocations. We find that inefficiencies in the labor allocation and entry between sectors, as well as inefficient selection and output per firm within sectors, generate welfare losses of about 6%–10% of GDP."
            "en" => "Equilibria and optima generally differ in imperfectly competitive markets. Although this is well understood theoretically, it is unclear how large the welfare distortions are in the aggregate economy. Do they matter quantitatively? To answer this question, we develop a multisector monopolistic competition model with endogenous firm entry and selection, productivity, and markups. Using French and UK data, we quantify the gap between the equilibrium and optimal allocations. We find that inefficiencies in the labor allocation and entry between sectors, as well as inefficient selection and output per firm within sectors, generate welfare losses of about 6%–10% of GDP."

By matching employer–employee data with trade data at the firm level we show that the export experience acquired by managers in previous firms leads their current firm toward higher export performance, and commands a sizeable wage premium for the manager. Moreover, export knowledge is decisive when it is market-specific: managers with experience related to markets served by their current firm receive an even higher wage premium; firms are more likely to enter markets where their managers have experience; exporters are more likely to stay in those markets, and their sales are on average higher. Our findings are robust to controlling for unobserved heterogeneity and, more broadly, endogeneity and indicate that managers' export experience is a first-order feature in the data with an impact on a firm's export performance that is, for example, at least as strong as that of firm productivity."

              Dans cet article nous considérons un jeu de duopole en deux étapes, dans lequel les entreprises décident d’abord si elles souhaitent investir dans la publicité, puis se concurrencent ensuite en prix. Nous montrons que la publicité a deux effets : d’une part, elle élargie le marché pour les deux entreprises, et d’autre part, elle redirige une partie de la demande vers le produit publicisé.\n
              Nous obtenons, en fonction des paramètres, des équilibres symétrique et asymétriques. Les deux cas les plus intéressants sont un jeu de coordination, où les deux entreprises peuvent simultanément investir ou ne pas investir, et un jeu chicken, où seule l’une des deux entreprises investie tandis que l’autre peut éventuellement sortir (de manière endogène) du marché. Nos résultats suggèrent que la différenciation des produits joue un rôle ambigu sur l’investissement en publicité et qu’une substituabilité forte entre produits peut donner lieu à un problème de coordination.

              In this paper we consider a two-stage duopoly game where firms first decide whether to invest in advertising and then compete in prices. Advertising has two effects : a market enlargement for both firms and a predatory gain for the investing firm only.\n
              Both symmetric and asymmetric equilibria may arise. The two most interesting cases are a coordination game where both firms investing and non-investing are equilibria, and a chicken game where only one firm invests while the other is possibly driven (endogenously) out of the market. Our results suggest that product differentiation has an ambiguous impact on investment in advertising and that strong product substitutability may induce a coordination problem.

In doing so, we provide an exact decomposition of revenue productivity in terms of the underlying heterogeneities, thus bridging the gap between quantity and revenue productivity estimations. We use Belgian firms production data to quantify TFP, demand and markups and show how they are correlated with each other, across time and with measures obtained from other approaches. In doing so, we find quantity TFP and demand to be strongly negatively correlated with each other so suggesting a trade-off between the quality of a firm’s products and their production cost. We also show how our framework provides deeper and sharper insights on the response of firms to increasing import competition from China.

However, while the various micro foundations of agglomeration externalities stress the importance of total factor productivity (TFP), the empirical evidence on agglomeration externalities rests on measures obtained using firm revenue or value-added as a measure of firm output: revenue-based TFP (TFP-R). This article uses data on French manufacturing firms’ revenue, quantity, and prices to estimate TFP and TFP-R and decompose the latter into various elements. Our analysis suggests that the revenue productivity advantage of denser areas is mainly driven by higher prices charged rather than differences in TFP. At the same time, firms in denser areas are able to sell higher quantities and generate higher revenues, despite higher prices. These and other results we document suggest that firms in denser areas are able to charge higher prices because they sell higher demand/quality products. In this respect, two key elements related to this capacity to sell more at higher prices are the degree of vertical differentiation and trade cost, with products characterized by higher vertical differentiation and/or lower trade costs featuring stronger patterns and driving overall results."
