Robotizing to Compete? Firm-level Evidence
Author:
Abstract:
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 Central and Eastern European countries in the 1990s. We find that firms facing greater competition in export markets tend to reduce investments in automation technologies. These average negative effects are driven by the least productive firms, while the most efficient exporters in industries that are more prone to automation tend to robotize in order to compete. These findings suggest that an increase in the degree of product market competition widens disparities between firms.

Revisiting the Trade-Creating Effects of Non-Tariff Barriers
Author:
Abstract:
Modern regional trade agreements focus on promoting bilateral exchange mostly by lowering non-tariff barriers to trade. But do existing regional trade agreements actually deliver what they promise? This paper argues that existing results in the literature are upward biased because of measurement error in a crucial control variable: tariff rates. Using a novel data set of high-quality tariff information, the paper shows that, on average, non-tariff barriers reductions in deep regional trade agreements boost services trade but not goods trade. Estimating separate non-tariff barrier effects for each regional trade agreement reveals strong heterogeneity: only 23 percent of all regional trade agreements seem to lower non-tariff barriers. For most regional trade agreements, we fail to find any significant effect, while 9 percent appear to reduce trade, possibly because a more balanced regulation evens out comparative advantages. The trade agreements that foster trade the most include non-discriminatory trade policy changes.

Missing Tariffs
Author:
Abstract:
Many studies use tariffs to measure changes in trade policy. This paper shows that standard sources for tariffs suffer from substantial measurement error due to misreporting and the resulting false imputation: Countries fail to report tariffs every year and missing data are more prevalent for preferential than for most favored nation (MFN) tariffs. WITS, the main data provider for tariffs, falsely interpolates missing preferential tariffs with MFN tariffs. This practice leads to artificial spikes in bilateral time series data and, hence, induces massive measurement error. I introduce a new global tariff dataset at the six-digit product level for 197 countries and 30 years that combines five different sources for tariffs and proposes a new interpolation algorithm taking the misreporting into account. Lastly, I show using gravity that correcting for the messy data increases the estimates of the trade elasticity by 2.89 times.

Demand and Supply Side Linkages in Exporting Multiproduct Firms
Author:
Abstract:
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 cannibalization effect. On the supply side, joint inputs can create a dependency of one product's marginal costs on the output of other products. The existence of these linkages is important for how firms respond to shocks and has major implications for several performance measures, such as productivity and markups. This paper provides first empirical evidence for the existence of cannibalization linkages in presence of supply linkages, which is implied evidence for market power.

Inefficient Labor Market Sorting
Author:
Abstract:
A growing empirical literature attributes much of the productivity advantages of large, "superstar" firms to their adoption of best practice management techniques that allow them to better identify and use talented workers. The reasons for the incomplete adoption of these "structured management practices" and their welfare implications are not well understood. This paper provides a positive and normative analysis of these issues in a theoretical framework in which structured management practices induce sorting of talent across firms. Incomplete adoption arises because worker talent is in limited supply. In equilibrium there is excessive adoption of structured management practices and too much sorting of talented workers into large firms. In this second-best environment, policy changes that favor large firms, such as trade liberalization, have the potential to lower welfare.

Export Induced Spatial Divergence
Author:
Abstract:
How does export liberalization affect firm location choice and the spatial concentration of economic activity? We address these questions using the geo-coordinates of Chinese manufacturing firms and find that export widens inter-city and intra-city spatial disparities by reinforcing initially large industry centers. We first show that there has been an increased spatial concentration across cities in response to improved foreign market access. Only industry city pairs that were large initially increase their employment density following trade liberalization. Second, there has also been an increased spatial concentration within cities. For a given industry, districts closer to city centers are getting denser, mainly driven by the extensive margin. Third, the above effects are not exclusive to industries directly exposed to export shocks but also spill over positively to upstream and downstream industries and negatively to industries competing for the same workers locally.

The Spillover Effect of Services Offshoring on Local Labour Markets
Author:
Abstract:
I provide new empirical evidence on the direct and indirect impact of services offshoring on local employment and wages, using a unique dataset on firms in the UK for the period 2000-2015. Exploiting variation in firms' services offshoring across labour markets, I show positive aggregate local labour employment and wage elasticity to services offshoring. Spillovers from offshoring to non-offshoring firms explain the positive results, and services offshoring complementary to firms' production has a larger effect than the offshoring competing with firms' outputs. Finally, I show that services offshoring widens firms' employment and wage dispersion within local labour markets.

Trade Exposure and the Decline in Collective Bargaining: Evidence from Germany
Author:
Abstract:
We analyze the effect of the increase in trade exposure induced by the rise of China and the transformation of Eastern Europe on collective bargaining coverage of German plants in the period 1996-2008. We exploit cross-industry variation in trade exposure and use trade flows of other high-income countries as instruments for German trade exposure. We find that increased import exposure has led to an increase in the probability of German plants leaving industry-wide bargaining agreements, accounting for about one fifth of the overall decline in the German manufacturing sector. The effect is most pronounced for small and medium-sized plants.

Dissecting Between-Plant and Within-Plant Wage Dispersion - Evidence from Germany
Author:
Abstract:
Using rich linked employer-employee data for (West) Germany between 1996 and 2014, we analyze the most important drivers of the recent rise in German wage dispersion and pin down the relative contribution of plant and worker characteristics. Moreover, we separately investigate the drivers of between-plant and within-plant wage dispersion. We also analyze the sources of the recent slowdown in German wage inequality and compare the results for West Germany to the ones for East Germany. We disentangle the relative contribution of each single variable to the rise in wage dispersion using recentered influence function (RIF) regressions. The most important drivers of wage dispersion are industry effects and the bargaining regime. The former predominantly works through the wage structure effect while, in the latter case, both the decline in collective bargaining coverage and the strong increase in wage dispersion within the group of covered plants have played a substantial role. While education has been another factor contributing to both between-plant and within-plant wage inequality, other candidate factors such as plant size, the exporting status, plant technology, and investment intensity are all of little if any direct quantitative importance for the increase in wage dispersion.
