Defensive hiring of researchers by incumbent firms with monopsony power reduces creative destruction. This mechanism helps explain the simultaneous rise in R&D spending and decline in TFP growth in the US economy over recent decades. We develop a simple model highlighting the critical role of...

The optimal capital income tax rate has been shown to be nonzero in overlapping generations (OLG) models, as it helps redistribute income between cohorts and individuals with different labor supply elasticities and individual productivities. We show in a medium-scale OLG model that the optimal...

History shows militarily dominant states that pursue imperialism, relying on their might to extort resources from weaker states. Occasionally, the latter revolt and the dominant state suffers some casualties. This paper explores imperialism along steady-growth paths. If the dominant state...

Heterogeneous monopolists produce goods using either brown technology, which relies on labor and carbon energy, or green technology, which relies solely on labor. R&D firms enhance productivity using labor to outcompete existing monopolists, thereby driving economic growth. The extraction of...

Fertility rates have declined dramatically across almost all highincome countries over the past decades. This has raised concerns about future economic prospects. Indeed, fully- and semi-endogenous growth models imply that a shrinking workforce would lead to declining income growth and perhaps...

This paper explores how civic capital shapes the relationship between government size and economic performance. Building on an exogenousgrowth version of Barro (1990), we incorporate O-ring technology to capture task complementarity in the public sector, highlighting the role of civic capital in...

The neo-Schumpeterian growth models, which appeared in the early 1990s, have ostensibly reintroduced the entrepreneur into mainstream growth theory. However, we show that by ignoring genuine uncertainty and by assuming that profits follow an objectively true and ex ante known probability...

This study examines the impact of regional innovation factors and their dynamic interactions on regional economic growth. Using a 10-year panel dataset from 17 provinces and cities in South Korea, we analyze the data using panel data regression and explore non-linear relationships with the...

Scrutinizing post-Keynesian theory of endogenous technical progress and Régulation Theory, this paper examines productivity growth and its variation within capitalist economies. The aim is to identify how institutions steer productivity growth. Based on the vast literature demonstrating that...

This paper provides novel empirical evidence on the impact of monetary policy on innovation investment using unique firm-level data. First, we document the effect of a large, systematic monetary tightening (ECB rate increases from 0% to 4.5% during 2022-23), with average firm-level innovation...

Technological change, an overwhelming fact in recent socioeconomic history, involves, as Joseph A. Schumpeter famously put it, "creative destruction" on a large scale: it gives rise to new goods, production methods, firms, organisations, and jobs, while rendering some received ones obsolete. Its...

This research conducts a comparative study of the economic growth and income distribution effects of consumption and comprehensive income taxes by introducing them into an endogenous economic growth model with human capital formation. We obtained the following results. First, consumption tax...

We build an endogenous growth model that distinguishes productive and welfare government expenditures and embeds fiscal externalities. The model yields three testable hypotheses: (i) productive expenditure raises growth (Barro effect); (ii) productive expenditure generates cross-country...

We study clean energy production subsidies in a quantitative climate-economy model. Clean energy production subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient production subsidy equals the marginal external cost of dirty...

This paper provides novel empirical evidence on the impact of monetary policy on innovation investment using unique firm-level data. First, we document the ef- fect of a large, systematic monetary tightening (ECB rate increases from 0% to 4.5% during 2022-23), with average firm-level innovation...

I investigate how taxing immigrants and redistributing the collected funds as educational subsidies influence human capital accumulation and growth in the source economy. The analysis is performed in a two-country growth model with endogenous fertility, in which public knowledge spillovers from...

What sparked humanity's leap from stagnation to prosperity? What lies at the core of inequality among nations? Unified Growth Theory explores the evolution of societies over the entire course of human history. It uncovers the universal wheels of change that have governed the journey of humanity,...
