 The paper ‘The Paradox of Search Intensity’ by Ph.D. He Chao, Associate Professor of China Economy Research Institute of Liaoning University and Ph.D. Fan Xiaodong, Senior Lecturer of Monash University in Australia was accepted by the Journal of Economic Theory (JET), a top journal in theoretical economics.

Its acceptance is another landmark achievement in terms of Liaoning University’s ‘Double First-class’ development in recent years with teachers from the Faculty of Economics publishing a slew of academic papers in international journals such as RESTAT (Yu Miaojie), JPubE (Chen Feng), JDE (Yu Miaojie, Yin Lijuan), JEMS (Gaoming) and JLE (Yang Zhe).

 

 Introduction to the paper

In the standard labor search matching model, the search intensity of unemployed workers is pro-cyclical (the worse the economy, the lower the search intensity) and the higher the search intensity of workers will increase the matching efficiency and the incentive for enterprises to create jobs. These two forecasts are inconsistent with the situation of the US labor market after the 2008 financial crisis. To solve the problem of inconsistency between theory and data, this paper allows workers to find jobs in multiple markets at the same time in the standard model of discrete time and may be admitted in multiple markets. At this time, adverse economic shocks can improve the intensity of workers’ search because as the probability of finding a job in the local area decreases, workers will be more motivated to find a job in more markets. In contrast, in the standard model of continuous time and single market, the marginal return of search intensity does not depend on the return of existing search intensity, so the search intensity is pro-cyclical. This increase in the breadth of search intensity will lead to more job admissions being rejected, which in turn will inhibit the employment creation of enterprises and reduce the matching efficiency. The externality of admission rejection may also lead to multiple equilibria. In the calibrated model, a short-term financial crisis can lead to the continuous increase of workers’ search intensity and unemployment rate. Financial shocks are more likely to cause this result than productivity shocks.
