Investments in energy technologies are substantially governed by climate policy. We demonstrate analytically that price-based instruments, such as carbon-taxes, and quantity-based regulations, like emission trading systems, have distinct effects on the (co-)variance of power plant profits. If...

This paper examines the Lucas Paradox and the Allocation Puzzle of international capital flows referring to a panel data set of EMU countries and major industrialized and emerging economies. Overall, the results do not provide evidence in favour of the Lucas Paradox and the Allocation Puzzle....

I calculate unemployment multipliers of fiscal consolidation policies in a standard, closed-economy New Keynesian framework with search and matching frictions, and, as an innovation, in the presence of sectoral heterogeneity. Family and non-family firms behave differently in the labor market and...

In this paper, we propose to explain capital accumulation in a stochastic framework by taking into account the two main motives for investment. Specifically, firms invest to expand capacity and to replace old machines. The model considers irreversible investment under uncertainty and embodied...

In this paper, we extend the usual models of irreversible investment under uncertainty by introducing the stock of public capital as an input for the private sector. Public investment takes place in a stochastic environment. Public capital then increases the productivity of private capital which...

We present a model in which banks and other financial intermediaries face both occasionally binding borrowing constraints, and costs of equity issuance. Near the steady state, these intermediaries can raise equity finance at no cost through retained earnings. However, even moderately large...

In this paper the standard Euler equation investment model with imperfectly competitive product markets is extended for imperfectly competitive structures on the factor markets: labour markets and markets for investment goods. This extension leads to two additional explanatory variables in the...

Unification fundamentally changed the terms of quantitative macroeconomic analysis for Germany. Two main areas concerned are data availability for the eastern part of Germany and structural changes within the behavioural equations after unification. Our paper presents results from the estimation...

Price setting has become more flexible following a string of large adverse shocks (Covid-19, the Ukraine War). We argue that a shift to a high-uncertainty regime incentivizes firms to invest in their ability to adjust prices. We formalize this idea in a general equilibrium model with endogenous...

In a structural dynamic model that incorporates two broad production sectors with different carbon emissions, we find that climate policy uncertainty (CPU) shocks (i) lower the market value of the highly carbon-emitting sector relative to the low carbon-emitting sector, and (ii) reduce real...
