In den Jahren 2020 bis 2023 gab es vergleichsweise große Schwankungen im Aufbau und Abbau von Arbeitsplätzen. Dieses Phänomen wird hier auf gesamtwirtschaftlicher und branchenspezifischer Ebene untersucht, um aufzuzeigen, wie sich die Dynamik am Arbeitsmarkt im Lichte der jüngsten Schocks...

This paper examines the resource mismatch in China's healthcare sector from 2010 to 2019. We use structural efficiency to measure the resource mismatch in the healthcare industry (0.2-0.7). We find that an increase in the proportion of private hospitals decreases the healthcare resource mismatch...

Children tend to choose the same occupations as their parents. We examine the implications of this tendency for talent allocation and intergenerational mobility. Using Swedish data on skills and personality traits, we estimate a general equilibrium Roy model with unequal occupational access...

We develop a methodology to estimate the cost of capital using credit registry microdata, and apply it to study capital allocation efficiency in the United States. Our measure incorporates the contractual interest rate, expected default probability, recovery rate, and expectations of future...

This paper develops a nonlinear optimization model for the optimal allocation of labor and investment resources in a three-sector open economy. The model is based on the Cobb-Douglas production function and incorporates sectoral interdependencies, capital depreciation, trade balances, and import...

The productivity growth of the Greek economy has stagnated since the 2010 European Debt Crisis. Despite reforms in product market regulations; their impact on productivity has been mixed. Firm-level data shows that resource misallocation worsened from 2009 to 2020; especially in non-tradable...

Ever since their independence, African countries have engaged in a series of treaties creating 8 Regional Economic Communities (RECs) that were (and still are) to pilot this integration starting with a Free Trade Area (FTA) followed by a customs union, a common market, and a monetary union...

The issue of introducing a vulnerability indicator in an aid allocation formula such as the Performance Based Allocation (PBA) used by several Multilateral Development Banks (MDBs) has been discussed for a long time. Three reasons make it particularly desirable to now reconsider the issue.

We argue that capital misallocation arises endogenously due to incomplete consumption insurance. We model risk-averse entrepreneurs with heterogeneous productivity who face idiosyncratic output shocks and choose how much capital to rent before uncertainty unfolds. We show that incomplete markets...

We revisit the size-volatility relationship in firm growth using administrative data on French manufacturing firms. Departing from the log-log linear decay commonly reported by other studies, we find a two-regime pattern: volatility declines steeply with size for small firms, but flattens for...

This paper characterizes the short- and long-run Cournot equilibrium with heterogeneous firms and stochastic technological change. In our model, firms have different technologies with heterogeneous fixed and variable costs and various degrees of markups. In a framework with homogeneous firms,...

We examine the effects of international trade in the presence of a set of domestic distortions giving rise to informality, a prevalent phenomenon in developing countries. In our quantitative model, the informal sector arises from burdensome taxes and regulations that are imperfectly enforced by...

We study a large market model of dynamic matching with no monetary transfers and a continuum of agents who have to be assigned items at each date. When the social planner can only elicit ordinal agents' preferences, we prove that under a mild regularity assumption, incentive compatible and...

Background: Each disaster has its specific resource requirements, varying based on its size, location, and the affected region's socio-economic level. Pre-disaster planning and post-disaster dynamic resource allocation including material and human resources is essential. Methods: To address the...

We show that in a canonical model with heterogeneous entrepreneurs, financial frictions, and an imperfectly elastic supply of capital, a fall in the interest rate has an ambiguous effect on aggregate economic activity. In partial equilibrium, a lower interest rate raises aggregate investment...

Against the backdrop of production and sales globalization, a country can utilize its trade network position to secure greater benefits from international trade and gradually enhance its economic and trade influence. This process is inseparable from the rational allocation of production factors....

The high costs in the European Union of supplying electricity can only be structurally reduced through decarbonisation and deeper European electricity system integration. In the short-term, policymakers have few choices. They can redistribute system costs by shifting components from one consumer...
