This paper reveals a new determinant of wage markdowns at the firm level, namely, the product scope. Using matched employer-employee data on Danish manufacturing firms, we document a negative elasticity between wages and firm scope, which is of a similar magnitude but opposite sign as the...

Based on the sufficient statistics approach developed by Huang and Ottaviano (2024), we show how the state of technology of European industries relative to the rest of the world can be empirically assessed in a way that is simple in terms of computation, parsimonious in terms of data...

We propose a new model of multi-product firms in international trade, where firms choose their product mix based on the products’ attractiveness and endogenous competition. The model is motivated by two novel stylized facts using Danish manufacturing data, which demonstrate the importance of...

We study how increased import competition affects the evolution of productivity in a small open economy. We use a production survey of Belgian firms where we observe quarterly firm-product data at the 8-digit level on value and quantities sold together with firm-level labor, capital, and...

I would like to thank Hong and Luparello (2024) for their effort in replicating, as well as partially extending, the results in Orr (2022). This replication report makes what I believe to be three key points: 1. The replication package of Orr (2022) is computationally reproducible (up to two...

This paper investigates the bilateral impacts of antidumping measures, beyond directly targeted products and exporting firms. It focuses on the country whose exports are most exposed to such measures, China. Product-level analysis shows that export volumes are negatively affected for products...

Climate change is one of the pressing issues of our time, and carbon emissions caused by industrial production are among its most important drivers. This paper analyses how multi-product firms adjust to an increase in the cost of emissions (e.g. due to the introduction of emissions pricing) in...

I analyze a model of directed search in which a consumer inspects a finite number of products sharing attributes with each others. The consumer discovers her valuation for the attributes of the inspected products and adapts her search strategy based on what she has learned. The consumer...

This paper aims to understand the pathways by which exporters become entities that sell multiple goods to multiple customers. To understand firms' export strategies, we analyse new trade flows - new seller-buyer-product combinations - of individual exporters. Our first finding highlights that...

Which products are potentially produced together? When demand for a product increases, which firms will supply it? Using multi-product production patterns within and across firms, we recover a continuous cost-based distance between firms and unproduced products. Higher product distance implies...

Despite the various industrial applications integrating inbound transportation, production, and inventory, only single-product studies have been conducted addressing the related production and inventory routing problems simultaneously. To meet the optimization requirements of many-to-one...

I study a vertically differentiated product market intermediated by a monopoly platform. A monopoly seller offers a low- and a high-quality product to consumers with heterogenous preferences to purchase through the platform rather than directly from the seller. Absent any restrictions imposed by...

Products produced by a multiproduct firm can be linked through demand linkages or supply linkages. On the demand side, changes in the price of one product can affect the demand for a firm's other products through shifts in consumer expenditures. This is commonly referred to as the...

Whether there exists a dual-product market in China. In fact, there are obvious distribution differences between low-end products and high-end products, which are dominated by low-end products in a "pyramid" shape. This paper explores the resource allocation in multi-product firms based on the...

This study designs a method to estimate the productivity of exported products by combining custom and firm survey data. To build a productivity link between imports and exports, we also estimate the contribution of import scope to productivity. By using micro data during trade liberalization in...

Companies can gain significant advantages from the integrated optimization of production, inventory, and routing in a supply chain. The production routing problem (PRP), which aims to jointly optimize production, inventory, and vehicle routing, is motivated in this fashion. In actuality, the...

The past few decades have witnessed a slowdown in productivity growth in many advanced economies, including Finland. Against this backdrop, this study investigates product switching in Finnish manufacturing firms during the period of 2009-2019. The findings indicate a growing trend towards...

This paper proposes a novel method to estimate productivity and quality at the firm-product level, together with transformation function and demand parameters. The method relies on firm optimization conditions to obtain a one-to-one mapping between observed data and unobserved productivity and...

We investigate the impact of product market competition on firms’ automation investments. We use a rich combination of micro-data on Portuguese exporters and exploit a novel source of variation in the degree of competition they face – a tariff liberalization between the European Union and...

A fundamental result in the theory of commodity taxation is that taxes increase consumer prices and reduce supply, aggravating the distortions caused by market power. This result hinges on the assumption that each firm provides a single product. We study the effects of commodity taxes in...

We consider mergers between multi-product firms in a market with monopolistically competitive fringe of single-product firms. Aggregate product variety is determined by product variety choices of multi-product firms and entry/exit decisions of single-product firms. Mergers can generate marginal...

Standard horizontal FDI models predict substitutability between FDI and exports in light of the proximity-concentration trade-off, nonetheless, empirical literature finds, almost invariably, a complementarity effect. We argue that given the multi-product nature of the vast majority of firms, FDI...

We consider an infinite-horizon multi-product dynamic pricing problem with reference effects in a monopolistic setting, where the reference price is an exponentially weighted average of historical prices. In each period, the demand follows the multinomial logit (MNL) model, where the utility...

We consider a dynamic pricing problem for consumer electronics trade-in program, where a firm buys and sells multiple types of pre-owned (used) products over a finite selling horizon. The trade-in program offers two options: trade-in for cash and trade-in for upgrade, where in the former...
