    Abstract: While innovation is a source of competitiveness, it may expose plants to survival risks. Using a rich set of plant-product data for Chilean manufacturing plants during the period 1996-2006 and discrete-time hazard models controlling for unobserved plant heterogeneity, this paper shows that innovating plants have higher survival odds. However, risk plays an important role for the innovation-survival link: only innovators that retain diversified sources of revenues survive longer. Single-product innovators are at greater risk of exiting. In addition, only innovators facing lower market risk, measured by fewer innovative competitors, low-pricing strategies, or lower sales volatility in the new products'markets, see their odds of survival increase significantly. Technical risk, measured by the proximity of product innovations to the plants'past expertise, the degree of sophistication of new products, or their novelty to the Chilean market, does not play a substantial role in the innovation-survival link. Engaging in risky innovation is not an irrational decision, since plants reap big payoffs -- higher productivity, employment and sales growth -- from such innovations. However, those payoffs are not always higher than those from cautious innovation, suggesting that constraining factors, such as credit constraints, force plants to take on more risk when innovating. An implication of the findings for industry dynamics is that among innovators, only the survival of cautious innovators is guaranteed. Since engaging in cautious innovation may not be feasible for all plants, there could be a role for policy in reducing innovators'exposure to risks and providing assistance to deal with failed innovations, while setting the right incentives.

    Abstract: In this paper, we propose an extension of the productivity decomposition method developed by Olley & Pakes (1996). This extension provides an accounting for the contributions of both firm entry and exit to aggregate productivity changes. It breaks down the contribution of surviving firms into a component accounting for changes in the firm-level distribution of productivity and another accounting for market share reallocations among those firms -- following the same methodology as the one proposed by Olley & Pakes (1996). We argue that the other decompositions that break-down aggregate productivity changes into these same four components introduce some biases in the measurement of the contributions of entry and exit. We apply our proposed decomposition to the large measured increases in Slovenian manufacturing during the 1995-2000 period -- and contrast our results with those other decompositions. We find that, over a 5 year period, the measurement bias associated with entry and exit is substantial, accounting for up to 10 percentage points of aggregate productivity growth. We also find that market share reallocations among surviving firms played a much more important role in driving aggregate productivity changes.

  3. By: Soham Baksi; Pinaki Bose; Di Xiang
    Abstract: For certain products, consumers' misinformation about quality is more endemic at intermediate levels of the quality spectrum rather than at the top or the bottom levels of quality. Using an oligopoly model of vertical product differentiation with three quality levels - green, natural, and brown - we examine the consequences of consumers' overestimation of the quality of the natural (i.e. intermediate quality) product. There are three firms in the market, with each type of firm producing the corresponding type of the product. The firms choose the quality level of their product before choosing its price (Bertrand case) or quantity (Cournot case). Irrespective of the nature of second stage competition, we find that quality overestimation by consumers increases profit of the natural firm, and motivates it to raise its product’s quality. In response, the green firm improves its quality even further, but ends up with lower profit. Overall, average quality of the vertically differentiated product improves, which raises consumer surplus. Social welfare increases when firms compete in prices but falls when they compete in quantities.
