Policy variability and economic growth

TLDR
In this paper, the authors explore the effect of policy variability on economic growth and welfare and find that the lack of persistence in policies per se need not be welfare reducing and that it is likely to decrease growth, but, by creating a stronger intertemporal link across regimes, variability reduces the fluctuation in investment rates, thus decreasing the magnitude of changes in consumption and increasing welfare.
Abstract
This paper explores the effect of policy variability (or frequency of regime switching) on economic growth and welfare. We study a one-sector growth model where investment can be subsidized at either a positive rate or not subsidized at all. We find that the lack of persistence in policies per se need not be welfare reducing and that it is likely to decrease growth. Higher variability implies more frequent changes in consumption and investment. But, by creating a stronger intertemporal link across regimes, variability reduces the fluctuation in investment rates, thus decreasing the magnitude of changes in consumption and increasing welfare.

Volatility and Development

TL;DR: In this paper, the authors identify four possible reasons why GDP growth is more volatile in poor countries than in rich ones: poor countries specialize in more volatile sectors, poor countries experience more frequent and more severe aggregate shocks (e.g. from macroeconomic policy), and poor countries' macroeconomic fluctuations are more highly correlated with the shocks of the sectors they specialize in.

On the ineffectiveness of tax policy in altering long-run growth: Harberger's superneutrality conjecture

TL;DR: In this article, the authors examined the growth effects of tax policy in the class of endogenous growth models driven by human capital accumulation, and numerical simulations of these models confirm the results Harberger predicted.

Policy Volatility, Institutions, and Economic Growth

TL;DR: This paper showed that a 1 standard deviation increase in policy volatility reduces long-term economic growth by about 0.74% in the panel regressions and by more than 1 percentage point in the cross-section.

Terms-of-trade uncertainty and economic growth

TL;DR: The authors examined a stochastic endogenous growth model in which terms-of-trade uncertainty affects savings and growth, and showed that increased terms of trade variability results in faster or slower growth depending on the degree of risk aversion.

Credit, Prices, and Crashes: Business Cycles with a Sudden Stop

TL;DR: In this article, the authors show that sudden stops can be the outcome of the equilibrium dynamics of a flexible-price economy with imperfect credit markets, and they question crisis-management policies seeking to impose direct controls on private capital flows and favor those that work to weaken credit frictions.

Distributive Politics and Economic Growth

TL;DR: This paper analyzed the relationship between economics and politics and concluded that inequality is conducive to the adoption of growth-retarding policies, and presented cross-country evidence consistent with it. But their analysis focused on how an economy's initial configuration of resources shapes the political struggle for income and wealth distribution, and how that, in turn, affects long run growth.

Long Run Policy Analysis and Long Run Growth

TL;DR: In this paper, the authors describe a class of models in which this type of heterogeneity in growth experiences can arise as a result of cross-country differences in government policy, which can also create incentives for labor migration from slow growing to fast growing countries.

Openness and Growth: A Time-Series, Cross-Country Analysis for Developing Countries

TL;DR: In this article, the authors compare the association between many popular proxies for openness and the rate of GDP growth, as well as the results from cross-section and panel estimation, controlling for country effects.

A Convex Model of Equilibrium Growth: Theory and Policy Implications

TL;DR: In this paper, the authors exposit a convex model of equilibrium growth and show that the long-run growth rate in per capita consumption depends on the parameters describing tastes, technology, and policies.
