Abstract
The paper seeks to identify the essential global-economic macro-shocks resulting from efforts by consumers, firms, or government policies to reduce social distancing, which caused a sharp temporary change in the world economy during the pandemic outbreak in the second quarter of 2020. The purpose is fulfilled using a simple two-period real-business cycle model. The observed reaction of the global economy in the second period of 2020 is measured by the deviation of the time series of GDP and its components, labor, labor income, and average labor product in the USA and EU from the log-quadratic trend. The model can replicate the observed economic response by reducing the total factor productivity, labor demand, and labor supply—no need to assume sticky prices. As a sudden drop in performance is supposed, followed by a modest recovery already in the following period, it is not assumed that the government would be able to avert it in time with fiscal or monetary policy. Moreover, the assumption of variable prices and supply-side shocks does not support such a policy.
期刊介绍:
Croatian Operational Research Review (CRORR) is the journal which publishes original scientific papers from the area of operational research. The purpose is to publish papers from various aspects of operational research (OR) with the aim of presenting scientific ideas that will contribute both to theoretical development and practical application of OR. The scope of the journal covers the following subject areas: linear and non-linear programming, integer programing, combinatorial and discrete optimization, multi-objective programming, stohastic models and optimization, scheduling, macroeconomics, economic theory, game theory, statistics and econometrics, marketing and data analysis, information and decision support systems, banking, finance, insurance, environment, energy, health, neural networks and fuzzy systems, control theory, simulation, practical OR and applications. The audience includes both researchers and practitioners from the area of operations research, applied mathematics, statistics, econometrics, intelligent methods, simulation, and other areas included in the above list of topics. The journal has an international board of editors, consisting of more than 30 editors – university professors from Croatia, Slovenia, USA, Italy, Germany, Austria and other coutries.
