- 요약This dissertation consists of three chapters focusing on questions in monetary economics and information frictions. In Chapter 1, I study how multi-region firms set prices and form their expectations when paying attention to shocks is costly. To do so, I develop a dynamic general equilibrium model with multi-region, rationally inattentive firms in which firms collect information on both aggregate and region-specific shocks. I show that how firms organize their pricing decisions -- whether centrally at headquarters or decentralized to regional divisions affect the optimal information structure. When decisions are made at headquarters, firms allocate attention between overall demand and regional demand differences, ignoring the latter as geographic dispersion increases. In contrast, when decisions are decentralized, regional divisions focus solely on their own demand. I calibrate the model to U.S. Federal Reserve districts, matching the average within-firm across-regions relative price dispersion in NielsenIQ scanner data. In the calibrated model, monetary shocks have real effects that are six times larger under regional decision-making compared to headquarters, and region-specific shocks spill over to other regions when decisions are centralized. Empirically, scanner data reveals that, even after accounting for distance, product-level relative price dispersion between regions is smaller within the same retail chain than across different chains, a result qualitatively replicated by the model. In Chapter 2, joint with Hassan Afrouzi and Saroj Bhattarai, we provide theory and evidence that relative price shocks can cause aggregate inflation and act as aggregate supply shocks. Empirically, we show that exogenous positive energy price shocks have a positive impact not only on headline but also on U.S. core inflation while depressing U.S. real activity. In a two-sector monetary model with upstream and downstream sectors and heterogeneous price stickiness, we analytically characterize how upstream shocks propagate to prices. Using panel IV local projections, we show that the responsiveness of sectoral PCE prices to energy price shocks is in line with model predictions. Motivated by post-COVID inflation in the U.S., a model experiment shows that a one-time relative price shock generates persistent movements in headline and core inflation similar to those observed in the data, even in the absence of aggregate slack. The model also emphasizes that monetary policy stance plays an important role in propagation of such shocks. In Chapter 3, I study how a firm's composition of customer base affects its information acquisition about inflation and price-setting behavior. First, I use survey data of New Zealand firms to document that firms with a larger share of revenue coming from long-term customers have larger inflation backcast errors and higher subjective uncertainty about aggregate inflation. Then, to rationalize these empirical findings, I develop a static model with rationally inattentive firms face demand heterogeneity and set prices under Rational Inattention. I interpret long-term customers as consumers with low demand elasticity, while short-term customers are consumers with high demand elasticity. When firms have a larger share of revenue coming from low elasticity consumers (long-term customers), they have less incentive to pay attention to their marginal cost, which is affected by an aggregate shock, as mistakes in price-setting won't lead to large profit losses. On the aggregate, this enhances monetary non-neutrality.
