Price and Quality Dispersion in an Offshoring Market: Evidence from Semiconductor Production Services

We study cross-country differences in price and quality in the market for semiconductor wafer manufacturing services. Using a proprietary transaction-level data set, we document i) substantial constant-quality price differences across suppliers, and ii) shifts toward lower priced suppliers. Chinese producers on average charged 17% less than leading Taiwanese producers for otherwise identical products and increased their market share by 14.7 percentage points. The extent of cross-country price dispersion is also diminishing over a products life. A model with costs of switching suppliers is consistent with these pricing dynamics and can sustain realistic quality-adjusted price dispersion.

Labor and Capital Dynamics Under Financing Frictions

We assemble a new, quarterly panel dataset that links firms’ investment and financing to their employment and wages. In the data, wages and leverage are negatively related, both cross-sectionally and within firms. This pattern contradicts models in which firms insure workers against unemployment risk. We reconcile this fact with a model that integrates factor adjustment frictions and wage bargaining with costly external financing. In the model, the probability of default rises with debt. Because default incurs deadweight costs, the expected surplus over which firms and workers bargain falls, thus depressing wages. We show that raising financing costs reduces employment and wages, in line with recent reduced-form evidence.

Quality-Adjusted Price Measurement: A New Approach with Evidence from Semiconductors

Many markets exhibit price dispersion across suppliers of observationally identical goods. Statistical agencies typically assume this dispersion reflects unobserved quality, so standard price indexes do not incorporate price declines when buyers substitute toward lower-price suppliers. We show that long-run price differences across suppliers can be used to infer unobserved quality differences and propose an index that accommodates quality-adjusted price dispersion. Using transaction-level data on contract semiconductor manufacturing, we document substantial quality-adjusted price dispersion and confirm that a standard index is biased above our proposed index.
