We review the implications of the “core‐competence” model of multi‐product firms, including the “market‐size puzzle”: for most countries, the world market is much larger than the home market, while the costs of accessing foreign markets are relatively low; hence the model predicts that most domestic firms should export more of their core products than they sell domestically; yet, in practice, we do not observe this. Extending the model to allow for investment in export market penetration resolves the puzzle and Mexican data confirm its predictions: in particular, only the largest firms exhibit the dominance of exports over home sales.
Relying on firm-level data from Statistik Industri this note analyzes the evolution of productivity dynamics of Indonesian firms over the past 20 years (1990-2009). Economy-wide and sectoral productivity changes are decomposed into their two main components: changes due to the evolution of average productivity and changes due to 'allocative efficiency'. This decomposition shows that while during the 20 years both components have increased, the changes in allocative efficiency have been mainly driven by average productivity growth and less by increases in allocative efficiency, even if the latter has also improved during the period under analysis. Interestingly, the note shows that both average Total Factor Productivity (TFP) growth and allocative efficiency improvements are especially driven by a few sectors: electronics, machinery and instruments, and textiles, clothing and footwear. Limited improvements in both allocative efficiency and average TFP have occurred instead in natural-resource-based sectors, sectors characterized by more limited competition and higher rents. This note emphasizes the importance of 'allocative efficiency' for productivity evolution because, in a context where firms are very different in their productivity, it becomes crucial how resources are allocated in the economy. This series of policy notes suggests that regulatory reforms, exposure to foreign competition and access to imported intermediate inputs are important determinants of allocative efficiency. The problem of a 'missing middle' is closely related to that of sub-optimal allocation of resources across firms: a strong feature of Indonesian firm-size distribution. Going further, the note suggests that burdensome regulations and imperfect financial markets are two important causes of this missing middle. To complement the focus on productivity, the note also analyzes firm-level job dynamics and points to the crucial role of 'start-ups' and new companies as a key driver of job creation. This finding suggests that the focus of policymakers on Small and Medium Enterprises (SMEs) may be misplaced and that this focus should start realigning towards supporting more dynamic 'start-ups' rather than SMEs.
This study examines developments at the plant-product level preceding an expansion into foreign markets. It relies on very detailed Mexican data for 1994-2004, a period of liberalization in US trade policy vis a vis Mexico, mandated by the North American Free Trade Agreement. Our approach is novel in that we focus on quality, proxied by domestic price premium, of current and future export products. Our findings are consistent with quality upgrading taking place in preparation for entry into export markets. We show that manufacturers who export a particular product variety tend to obtain a price premium for their domestic sales of this variety. Consistently with the hypothesis of quality upgrading before exporting, we find evidence that this premium emerges exactly one year before a variety starts being exported. We find no evidence of upgrading after entering export markets. Our IV estimates suggest that the changes in the price premium are driven by the anticipated cuts in US tariffs and are particularly pronounced among producers exhibiting better performance in the initial period.
This paper examines the effect of Walmart's entry into Mexico on Mexican manufacturers of consumer goods. Guided by firm interviews that suggested substantial heterogeneity across firms in how they responded to Walmart's entry, we develop a dynamic industry model in which firms decide whether to sell their products through Walmex (short for Walmart de Mexico), or use traditional retailers. Walmex provides access to a larger market, but it puts continuous pressure on its suppliers to improve their product's appeal, and it forces them to accept relatively low prices relative to product appeal. Simulations of the model show that the arrival of Walmex separates potential suppliers into two groups. Those with relatively high-appeal products choose Walmex as their retailer, whereas those with lower appeal products do not. For the industry as a whole, the model predicts that the associated market share reallocations, adjustments in innovative effort, and exit patterns increase productivity and the rate of innovation. These predictions accord well with the results from our firm interviews. The model's predictions are also supported by establishment-level panel data that characterize Mexican producers' domestic sales, investments, and productivity gains in states with differing levels of Walmex presence during the years 1994 to 2002.
Policy attitude towards trade integration and foreign direct investment (FDI) is often a controversial yet popular subject. This note presents evidences from recent policy researches that arguing that engaging in an open trade and investment regime have brought productivity gains which is key factor for sustaining increase in income per-capita. Evidence from Indonesia also suggests that foreign owned plants have become increasingly important, generating a significant share of exports and overall output, as well as more productive and more export intensive than domestic plants, and to spend more on RD and training. FDI also have positive impact on firms in the same sector, through competition and demonstration effects, and in upstream sectors, as suppliers to foreign-owned plants improve the quality of their own products to meet their clients more exacting needs. Evidence also suggests a positive impact from import competition in improving allocative efficiency across manufacturing plants which is a key element in driving productivity in manufacturing sector.
Recent research on international trade focuses on firm‐product‐level heterogeneity and the role of uncertainty in shaping international trade. This article contributes to the literature by examining product‐level dynamics within firms in the context of Mexican trade integration under NAFTA. The data show intense product churning within firms and confirm the existence of within‐firm product heterogeneity. The data indicate that new exporters enter foreign markets with a small number of varieties, most of which were previously sold at home, and with a small export small volume. The data also suggest that export discoveries are relatively rare and are imitated within a short period of time.
