Distributional Effect of Import Shocks on the British Local Labour Markets (Oxford Economic Papers)

This article investigates the causal effect of import shocks on wage distribution using individual-level data from the UK in the period 1997–2010. The analysis exploits regional variation in initial industrial structure and concentration for identification and applies a group IV quantile approach to estimate the effect of import shocks on workers at different parts of the wage distribution. The study finds that the effect of import shocks generated by increased import competition is concentrated on the middle of the wage distribution: while the import shocks negatively and significantly affect workers at the bottom-middle of the wage distribution, its effect on the very bottom and upper parts of the wage groups is insignificant. Moreover, the study finds that this labour market adjustment takes place through a reduction in the hourly wage rather than a decline in total hours worked.

Imports, FDI and Firm Performance (Review of International Economics)

This paper identifies the productivity gains from the number of inputs a firm chooses to import. Moreover, it analyses whether accounting for productivity gain from imported inputs changes the narrative around productivity gain from foreign direct investment. Using a firm-level dataset from Ethiopia, I find evidence of positive gains from combining domestic and imported inputs for both domestic and foreign-owned firms with the magnitude being larger for the latter. I also find limited evidence suggesting that accounting for productivity gains from imported inputs does affect gains from FDI. In our case, this indicates productivity gain from imported inputs and FDI are unrelated and there is neither substitutability nor complementarity between the two. Finally, I find a positive horizontal spillover and negative backward and forward spillovers.

Information Constraints and Technology Efficiency: Field Experiments Benchmarking Firms Website Performance (with Richard Kneller and Cher Li)

This study examines the role of peer-benchmarked information costs as a motivation to maintain the performance of digital technologies by firms. Leveraging two natural field experiments, we provided firms with bespoke reports that benchmarked their website performance against their peers. These distinct experimental frameworks enabled us to assess the salience of the information provided and the heterogeneity stemming from prior experience and potential for improvement. Our results suggest some modest effects from peer benchmarks on performance, although there is evidence of changes to the use of specific software tools that enhance website performance — key intermediate outcomes that serve as measurable indicators of efforts to change, aiming for longer-term performance gains.

Commuting and Residential Mobility: Evidence from the UK (work in progress)

This paper examines the effect of commuting on an individual's residential mobility preference using data from the UK household longitudinal study survey (Understanding Society). Together with the preference to move, the paper also assesses the impact of commuting on the expectation to move. For the identification strategy, I use a change in commuting time for those individuals who stay with the same employer and remain in the same place of residence. The paper finds that commuting increases the individual's intent to relocate and increases the expectation to move. The results contribute to the literature on the effect of commuting on residential choice and the subsequent labour market outcomes. Moreover, understanding the impact of commuting on individuals' preference to relocate has great policy implications, since the commuting and decision surrounding it are considered as the remedy to local economic problems.
