Welfare effects of controlling labor supply: an application of the stochastic Ramsey model
- 2003
-
Ingår i: Journal of Economic Dynamics and Control. - 0165-1889. ; 28:2, s. 331-348
-
Tidskriftsartikel (refereegranskat)abstract
- In this paper we extend Merton's (Rev. Econom. Stud. 42 (1975) 375) classic stochastic version of the Ramsey model by allowing the government to control the expected growth rate of the labor supply. We characterize the solution to this control problem for general time-separable preferences, and derive an analytical solution for the CRRA case. The results show to what extent the planner, or government, increases consumption and welfare by taking an active role in controlling the economy. We also explore the implications of government control of labor growth for the term structure of interest rates and the effects of taxes on capital.

Exploiting MIT Shocks in Heterogeneous-Agent Economies : The Impulse Response as a Numerical Derivative
- 2018

- We propose a new method for computing equilibria in heterogeneous-agent models with aggregate uncertainty. The idea relies on an assumption that linearization offers a good approximation; we share this assumption with existing linearization methods. However, unlike those methods, the approach here does not rely on direct derivation of first-order Taylor terms. It also does not use recursive methods, whereby aggregates and prices would be expressed as linear functions of the state, usually a very high-dimensional object (such as the wealth distribution). Rather, we rely merely on solving nonlinearly for a deterministic transition path: we study the equilibrium response to a single, small “MIT shock” carefully. We then regard this impulse response path as a numerical derivative in sequence space and hence provide our linearized solution directly using this path. The method can easily be extended to the case of many shocks and computation time rises linearly in the number of shocks. We also propose a set of checks on whether linearization is a good approximation. We assert that our method is the simplest and most transparent linearization technique among currently known methods. The key numerical tool required to implement it is value-function iteration, using a very limited set of state variables.

Distortions in the neoclassical growth model : A cross-country analysis
- 2014
-
Ingår i: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889 .- 1879-1743. ; 47, s. 1-19
-
Tidskriftsartikel (refereegranskat)abstract
- This paper investigates the properties of distortions that manifest themselves as wedges in the equilibrium conditions of the neoclassical growth model across a sample of 22 OECD countries for the 1970-2011 period. The quantitative relevance of each wedge and its robustness in generating fluctuations in macroeconomic aggregates is assessed. The efficiency wedge proves to be determinant in enabling models to replicate movements in output and investment, while the labor wedge is important to predict fluctuations in hours worked. Modeling distortions to the savings decision holds little quantitative or qualitative relevance. Also, investment seems to be the hardest aggregate to replicate, as prediction errors concerning output and hours worked are typically one order of magnitude smaller. These conclusions are statistically significant across the countries in the sample and are not limited to output drops. Finally, the geographical distance between countries and their degree of openness to trade are shown to contain information with regard to the wedges, stressing the importance of international mechanisms of transmission between distortions to the equilibrium conditions of the neoclassical growth model.

A Social Network Analysis of Occupational Segregation
- 2023
-
Ingår i: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889 .- 1879-1743. ; 147
-
Tidskriftsartikel (refereegranskat)abstract
- We propose an equilibrium interaction model of occupational segregation and labor market inequality between two social groups, generated exclusively through the documented tendency to refer informal job seekers of identical “social color”. The expected social color homophily in job referrals strategically induces distinct career choices for individuals from different social groups, which further translates into stable partial occupational segregation equilibria with sustained wage and employment inequality – in line with observed patterns of racial or gender labor market disparities. Supporting the qualitative analysis with a calibration and simulation exercise, we furthermore show that both first and second best utilitarian social optima entail segregation, any integration policy requiring explicit distributional concerns. Our framework highlights that the mere social interaction through homophilous contact networks can be a pivotal channel for the propagation and persistence of gender and racial labor market gaps, complementary to long studied mechanisms such as taste or statistical discrimination.

How tournament incentives affect asset markets: A comparison between winner-take-all tournaments and elimination contests
- 2017
-
Ingår i: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889. ; 75, s. 1-27
-
Tidskriftsartikel (refereegranskat)abstract
- We investigate the impact of investment managers׳ tournament incentives on investment strategies and market efficiency, distinguishing between winner-take-all tournaments (WTA), where a minority wins, and elimination contests (EC), where a majority wins. Theoretically, we show that investment managers play heterogeneous strategies in WTA and homogeneous strategies in EC, and markets are more prone to mispricing in WTA than in EC. Experimentally, we find that investment managers play more heterogeneous strategies in WTA than in EC, but this does not trigger significant differences in prices. Moreover, prices in WTA and EC do not differ significantly from markets composed of linearly incentivized subjects.

Do option-like incentives induce overvaluation? Evidence from experimental asset markets
- 2014

Ingår i: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889. ; 40, s. 179-194

Tidskriftsartikel (refereegranskat)abstract
- One potential reason for bubbles evolving prior to the financial crisis was excessive risk taking stemming from option-like incentive schemes in financial institutions. By running laboratory asset markets, we investigate the impact of option-like incentives on price formation and trading behavior. The main results are that (i) we observe significantly higher market prices with option-like incentives than linear incentives. (ii) We further find that option-like incentives provoke subjects to behave differently and to take more risk than subjects with linear incentives. (iii) We finally show that trading at inflated prices is rational for subjects with option-like incentives since it increases their expected payout. © 2014 Elsevier B.V.

Determinants of investor expectations and satisfaction. A study with financial professionals
- 2020
-
Ingår i: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889. ; 110
-
Tidskriftsartikel (refereegranskat)abstract
- We investigate determinants of price expectations and satisfaction levels of financial professionals and students. In experiments with 150 professionals and 576 students, we systematically vary price paths according to the final return (positive or negative) and the way in which the final return is achieved (upswing followed by downswing or vice versa). Professionals show the most optimistic price expectations and are most satisfied if assets fall in price first and then recover. In addition, professionals’ price expectations are highest after positive returns. Among students, qualitatively similar patterns emerge, but professionals’ price expectations are less prone to framing effects. © 2019 The Author(s)

Monetary policy trade-offs in an estimated open-economy DSGE model
- 2014

Ingår i: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889 .- 1879-1743. ; 42, s. 33-49

Tidskriftsartikel (refereegranskat)abstract
- This paper studies the trade-offs between stabilizing CPI inflation and alternative measures of the output gap in Ramses, the Riksbank's estimated dynamic stochastic general equilibrium (DSGE) model of a small open economy. Our main finding is that the trade-off between stabilizing CPI inflation and the output gap strongly depends on which concept of potential output in the output gap between output and potential output is used in the loss function. If potential output is defined as a smooth trend this trade-off is much more pronounced compared to the case when potential output is defined as the output level that would prevail if prices and wages were flexible.

Optimal monetary policy under learning and structural uncertainty in a New Keynesian model with a cost channel and inflation inertia
- 2016

Tidskriftsartikel (refereegranskat)abstract
- We investigate whether expectations-based optimal monetary policy rules under discretion and under commitment can enforce a determinate and least squares learnable rational expectations equilibrium (REE) in a New Keynesian model with inflation inertia and a cost channel of monetary policy transmission. Our numerical results show that commitment rules can enforce a determinate and learnable REE for all parameter constellations considered, whereas discretionary rules are not always able to enforce the same desirable outcome in the economy. We also examine different types of misapprehensions in policy-making and find that an incorrect assessment of the economy's true structure by the central bank greatly affects its capability to enforce a determinate and learnable, although suboptimal, REE. Thus, our numerical results highlight the relevance of this type of analysis for the design and conduct of monetary policy.

Delegation, time inconsistency and sustainable equilibrium
- 2009
-
Ingår i: Journal of Economic Dynamics and Control. - : Elsevier BV. - 0165-1889 .- 1879-1743. ; 33:8, s. 1617-1629
-
Tidskriftsartikel (refereegranskat)abstract
- This paper analyzes the effectiveness of delegation in solving the time inconsistency problem of monetary policy using a microfounded general equilibrium model where delegation and reappointment are explicitly included into the government's strategy. The method of Chari and Kehoe [1990. Sustainable plans. Journal of Political Economy 98 (4), 783–802] is applied to characterize the entire set of sustainable outcomes. Countering McCallum's [1995. Two fallacies concerning central-bank independence. American Economic Review 85 (2), 207–211] second fallacy, delegation is able to eliminate the time inconsistency problem, with the commitment policy being sustained under discretion for any intertemporal discount rate.
