This paper studies the aggregate implications of microeconomic investment irreversibility and idiosyncratic uncertainty in a simple growth model by highlighting real option effects. We endogenize the drift rate of real option by connecting it to the state of the economy. Thereby, we extend the...

Are uncertainty shocks a major source of business cycle fluctuations? This paper studies theeffect of a mean preserving shock to the variance of aggregate total factor productivity(macro uncertainty) and to the dispersion of entrepreneurs' idiosyncratic productivity (microuncertainty) in a...

Starting from the perspective of heterodox Keynesian-Minskyian-Kindlebergian financial economics, this paper begins by highlighting a number of mechanisms that contributed to the current financial crisis. These include excess liquidity, income polarisation, conflicts between financial and...

The European Union is currently making significant strides to lead on green finance and align its financial system with its climate, sustainability and clean energy ambitions. The Paris Climate Agreement, the G20 Green Finance Study Group and the G19 Hamburg Climate and Energy Action Plan have...

This study looks at firms' investment spending in fixed and intangible assets around three types of national elections: presidential, joint presidential, and legislative and parliamentary elections. Investments in fixed assets decline by up to 2% during presidential elections, and 4.44% in joint...

This paper studies the macroeconomic effects of shocks to idiosyncratic business risk in an economy with endogenously incomplete markets. I develop a model in which firms face idiosyncratic risk and obtain insurance from intermediaries through contracts akin to credit lines. Insurance is...

This paper studies the effects of changes in uncertainty on optimal leverage and investment in a dynamic firm-financing model in which firms have access to complete markets subject to collateral constraints. Entrepreneurs finance projects with their net worth and by issuing state-contingent...

Internal capital markets (ICMs) allow multinational enterprises (MNEs) to transfer liquidity globally, which connects external capital markets when the related entities also raise external funds. This paper studies such connection with a model of ICMs that permits two layers of agency problems:...

The interest rate is generally considered as a monetary policy tool and, at the same time, via Tobin's q, 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...

This paper investigates how cross-sectional micro-uncertainty influences the investment of small and large firms and discusses the aggregate implications of the heterogeneity in their investment decisions. Empirically, we find that large firms show less investment decline in times of heightened...
