The interest rate is generally considered as an important driver of macroeconomic investment. As an innovation, this paper derives the exact shape of the "hysteretic" impact of changes in the interest rate on macroeconomic investment under the scenarios of both certainty and uncertainty. We...

This paper investigates the method of matching regarding two crucial implementation choices, the distance measure and the type of algorithm. We implement optimal full matching - a fully efficient algorithm - and present a framework for statistical inference. The implementation uses data from the...

Observationally equivalent workers are paid higher wages in larger firms. This fact is often named as the "firm-size wage gap" and is regarded as a key empirical puzzle. Using micro-level data from Turkey, we document a new stylized fact: the firm-size wage gap is more pronounced for informal...

Understanding the selection of workers into informality is a policy priority to design programs to increase formalization across Sub-Saharan Africa, where nine out of ten workers are informal. This paper estimates a model of self-selection with entry barriers into the formal sector to identify...

This paper analyzes the joint dynamics of prices, output and employment across firms. We develop a dynamic equilibrium model of heterogeneous firms who compete for workers and customers in frictional labor and product markets. Idiosyncratic productivity and demand shocks have distinct...

In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

Financial frictions are known to raise the volatility of economies to shocks (e.g. Bernanke andGertler 1989). We follow this line of research to the labor literature concerned by the volatility of labor market outcomes to productivity shocks initiated by Shimer (2005): in an economy with search...

Several contributions have recently assessed the size of fiscal multipliers both in RBC models and New Keynesian models. None of the studies considers a model with frictional labour markets which is a crucial element, particularly at times in which much of the fiscal stimulus has been directed...

Using administrative data for West Germany, this paper investigates whether part of the urban wage premium stems from fierce competition in thick labour markets. We first establish that employers possess less wage-setting power in denser markets. Local differences in wage-setting power predict...
