Using a search and matching labor market equilibrium model, this paper quantifies lost labor productivity and consumption per worker that emerges from the restrictions on dismissals. Dismissal restrictions hamper the efficient reallocation of workers, with workers remaining longer in jobs. But...

According to search-matching theory, the Beveridge curve slopes downward because vacancies are filled more quickly when unemployment is high. Using monthly panel data for local labour markets in Sweden we find no (or only weak) evidence that high unemployment makes it easier to fill vacancies....

This paper disproves Diamond's search theory. Diamond transformed from an identity of employed workers and filled jobs to another of their surplus. This paper proves that such transformation is invalid, and that the resulting identity does not hold. This paper also proves that even the asset...

This paper proves that the Mortensen-Pissarides matching theory is nothing but a tautology. They started with an assumption and ended with the same as solution. Their assumption/solution is also at odds with the Beveridge, or the negative vacancy-unemployment relation

Using a novel database of 82.5 million online job postings, we show that employer skill requirements fell as the labor market improved from 2010 to 2014. We find that a 1 percentage point reduction in the local unemployment rate is associated with a roughly 0.27 percentage point reduction in the...

We propose a model to evaluate the U.K.’s zero-hours contract (ZHC) – a contract that exempts employers from the requirement to provide any minimum working hours, and allows workers to decline any workload. We find quantitatively mixed welfare effects of ZHCs. On one hand they unlock job...

We propose a model to evaluate the U.K.'s zero-hours contract (ZHC) - a contract that exempts employers from the requirement to provide any minimum working hours, and allows employees to decline any workload. We find quantitatively that ZHCs improve welfare by enabling firms with more volatile...

The impact of the Covid-19 pandemic on the UK labour market has been extremely heterogeneous across occupation and industrial sectors. Using novel data on job search, we document how individuals adjust their job search behaviour in response to changing employment patterns across occupations and...

The impact of the Covid-19 pandemic on the UK labour market has been extremely heterogeneous, with strong variation both by occupation and industrial sector. The extent to which workers adjust their job search behaviour in response to this reallocation of employment has an important bearing on...

The debate about the impact of robots on employment has been lively. In this paper, we examine the effect of robots on local labor demand in South Korea, one of the most technologically advanced countries in robotics. Using the regional variation in robot exposure constructed from national...
