In this paper we set up a baseline, but nevertheless advanced and complete model representing detailed goods market dynamics, heterogeneous labor markets, dual and cross-dual wage-price adjustment processes, as well as counter-cyclical government policies. The cyclical movements of output...

We estimate a dynamic, intertemporal optimisation model that mimics features of European labour markets, such as sticky nominal wages and sluggish adjustment of employment to shocks for 15 OECD countries. The estimates include a measure for the degree of labour market sluggishness that compares...

In this work, we investigate the interrelations among technology, output and employment in the different states of the U.S. economy (recessions vs. expansions). More precisely, we estimate different threshold vector auto-regression (TVAR) models with TFP, hours, and GDP, employing the latter as...

We examine the impact of corporate currency hedging on economic stability by introducing hedging activity in a Mundell-Fleming-Tobin framework for analyzing currency and financial crises. The ratio between hedged and unhedged firms is modelled depending on firm size as well as hedging costs. The...

This paper explores the linkage between corporate risk management strategies, investment, and economic stability in an open economy with a flexible exchange rate regime. Firms use currency futures contracts to manage their exchange rate exposure - caused by balance sheet effects as in Krugman...

Some financial disruptions that started in California, U.S., in March 2023, resulting in the closure of several medium-size U.S. banks, shed new light on the role of liquidity in business cycle dynamics. In the normal path of the business cycle, liquidity and output mutually interact. Small...

This paper presents a dynamic model of complex system dynamics vulnerable to loss of resilience, cycles, and contractions. We use a limit cycle model built upon Koçkesen & Semmler (2017) to evaluate Brunnermeirs’s theory of Resilience in the light of complex system dynamics and discuss the...

We evaluate Brunnermeir’s Theory of Resilience in the context of complex system dynamics where there however can be local and global resilience, vulnerability, loss of resilience, cycles, disruptive contractions, and persistent traps. In the paper, we refer to three-time scales. First, for...
