Lobbying for Regulations: When Big Business Says Yes (with Luca Macedoni)
Do firms universally oppose regulations that raise production costs, or do their stances depend on intrinsic characteristics that create uneven outcomes across businesses? This question is vital for understanding firms’ behavior in regulatory lobbying. We extend a standard general equilibrium model with firm heterogeneity in productivity by incorporating two key elements: (1) governments can impose regulations, and (2) firms can lobby for either stricter or more lenient regulations. While regulations aim to address consumption externalities, they also raise both marginal and fixed production costs. This can drive less productive firms out of the market, and leave surviving firms potentially better off. Our model shows that large firms are likely to lobby for stricter regulations when these regulations primarily increase fixed costs. To test these predictions, we use a guided machine learning algorithm to classify US firms’ positions on regulatory issues based on their lobbying reports. Our findings reveal that larger firms, particularly in concentrated industries, tend to support more stringent regulations. Additionally, we identify a negative relationship between capital intensity, leverage, and regulatory support, suggesting that a firm's operational flexibility plays a key role in shaping its stance on regulatory changes.
Prices and Immigration (with Ryan Kim and Justin Leung)
New draft coming soon!
While a large number of papers study the immigration inflow on labor market outcomes, studying the general equilibrium effect on prices and corresponding implications on real wages (and welfare) is scarce. There are three challenges. First, the immigration inflow is endogenous. Second, the immigration inflow affects prices through both increased product demand and increased labor supply. Third, the immigration inflow affects variety and quality, which are known to be of first-order importance in measuring the price index. We overcome these three challenges by using unique micro-level data that links barcode-level prices with the location of production, and identify immigration shocks at the supply and demand locations using an IV method at the frontier of the literature (Terry et al. 2024).
Vertical Integration and Financial Frictions (with Asli Leblebicioglu)
New draft coming soon!
We study a firms’ re-organization of production following an improvement in the efficiency of credit markets. A channel through which firm organization affects productivity is the Vertical Span of inputs that plants decide to produce “in-house” (Boehm and Oberfield, 2020). The vertical span captures the number of sequential production steps performed by the plant to produce their product. Credit constraints can distort production and sourcing decisions as they impede the firms’ use of external finance to source their inputs. Hence, a reduction in financial frictions can raise productivity through a change in the vertical span of production of the firm. In this paper we construct a measure of vertical span for Indian firms using data from the CMIE, which provides detailed information on both inputs and output of a panel of firms. To examine the effect of financial development on vertical span of production, we employ a difference-in-differences research design, where we consider an Indian judicial reform—establishment of Debt Recovery Tribunals— as the exogeneous credit supply shock. This reform, which increased banks’ ability to recover nonperforming loans, was introduced in a staggered manner across states. We find that firms in those states reduced their vertical span, implying that they produced inputs in-house that were closer to their output, and sourced more inputs that were further upstream. Consistently, plants outsourced a larger variety of inputs and the input share of total costs increased.
