Trade liberalization and wage inequality: Evidence from Korea

This paper investigates the heterogeneous income distribution effects of trade liberalization using Korean survey data from years of 2000–2015. Following the Stolper-Samuelson theorem most of previous research studying the effects of trade liberalization on wage differences focus on workers’ characteristics (e.g., skilled or unskilled) while heterogeneity within the same worker group has not been yet substantially investigated. To fill this gap, this paper provides empirical evidence of wage inequality across firms within the same group of workers caused by trade liberalization, potentially implied in the new-new trade models with firm heterogeneity. Employing a difference-in-differences (DID) specification, we find that the wages of unskilled workers in Korea have increased since its FTAs with more advanced countries, such as members of EU and the US, came into effect, while the effects on the wages of skilled workers are negative but not statistically significant. We also show that wage effects are heterogeneous across firms within unskilled and skilled worker groups, while the positive effects are statistically significant and largest for unskilled workers in medium-large sized firms. These findings are in line with both traditional and new-new trade models.     

Men at work. Wages and industriousness in southern Sweden 1500–1850

ABSTRACT

In his classic works on the industrious revolution, Jan de Vries argues that demand for new consumer goods trigged eighteenth century Europeans to work more. This implies that industrious behaviour and new consumption patterns were two parallel and interdependent processes that preceded the industrial revolution. However, there is an alternative explanation for any increase in labour output on household level, namely that the labourers were forced to work more to meet ends. An indication of this could be that day labourers’ relative wages decreased over time. In this article, we investigate this by studying wages from annual and casual labour in southern Sweden and compare their levels with consumption baskets.     

Stabilizing and destabilizing mechanisms: A new perspective to understand business cycles

Economists believe that economic fluctuations can be smoothed by stabilization mechanisms, such as price adjustment, embedded in the economy. While price adjustment can be seen as a stabilization mechanism, are there mechanisms that can destabilize an economy? We find that as early as 1939, Harrod discussed a destabilization mechanism, the firm's investment adjustment, illustrated in his knife-edge puzzle. We build a macro-dynamic model with investment and price as the core macroeconomic variables. Our analysis shows that the interaction between the stabilization mechanism (price adjustment) and the destabilization mechanism (investment adjustment) generates fluctuations and cycles. However, due to price stickiness, the price adjustment mechanism may not be enough to stabilize the economy. In this case, a government stabilization policy is necessary for further stabilization. As this paper also addresses the microfoundations of Keynesian quantity theory, including the choice of output and investment in optimization, it can be related to traditional Keynesian economics, with a new perspective to understand business cycles.     

Is self-employment really a bad experience? : The effects of previous self-employment on subsequent wage-employment wages

We use propensity score matching methods to quantify the effects of past self-employment experience on subsequent earnings in dependent employment using data on the population of Danish men observed between 1990 and 1996. Our results generally confirm existing studies in that we find that a spell of self-employment is associated with lower hourly wages compared to workers who were consecutively wage-employed. We also show, however, that this effect disappears—and even becomes positive in some settings—for formerly self-employed who find dependent employment in the same sector as their self-employment sector. Hence, the on average negative effect of self-employment is rather caused by sector switching than by the self-employment experience per se. Moreover, formerly self-employed who either enjoyed a high income or hired at least one worker during their self-employment spell receive wages in subsequent dependent employment that are at least as high as for individuals who have been consecutively wage-employed.     

Is there really a foreign ownership wage premium? Evidence from matched employer-employee data

Numerous studies on firm-level data have reported higher average wages in foreign-owned firms than in domestically owned firms. This, however, does not necessarily imply that the individual worker's wage increase with foreign ownership. Using detailed matched employer-employee data on the entire Swedish private sector, we examine the effect of foreign ownership on individual wages, controlling for individual and firm heterogeneity as well as for possible selection bias in foreign acquisitions. We distinguish between foreign greenfields and takeovers and compare foreign-owned firms with both domestic multinationals and local firms. Our results show a considerably smaller wage premium in foreign-owned firms than what has been found in studies conducted at a more aggregate level. Moreover, foreign takeovers of Swedish firms tend to have no or even a negative effect on wages.     

Do Newly Founded Firms Pay Lower Wages? First Evidence from Germany

Using a linked employer–employee data set for Germany, this paper analyses wage setting in a cohort of newly founded and other establishments from 1997 to 2001. While theory provides alternative explanations for higher or lower wages in newly founded firms, we show empirically that start-ups tend to pay lower wages, ceteris paribus. On average, wages in newly founded establishments are 8% lower than in similar incumbent firms. This negative wage differential is substantially smaller in eastern than in western Germany. The wage differential is shown to decline over time as the newly founded firms become more mature.     

Into the Mussa puzzle: monetary policy regimes and the real exchange rate in a small open economy

Industrial countries moving from fixed to floating exchange rate regimes experience dramatic rises in the variability of the real exchange rate. This evidence, forcefully documented by Mussa [Nominal exchange regimes and the behavior of real exchange rates: evidence and implications. Carnegie-Rochester Conference Series on Public Policy 25 (1986) 117], is a puzzle because it is hard to reconcile with the assumption of flexible prices. This paper lays out a dynamic general equilibrium model of a small open economy that combines nominal price rigidity with a systematic behavior of monetary policy able to approximate a continuum of exchange rate regimes. A version of the model with complete exchange rate pass-through is broadly consistent with Mussa’s findings. Most importantly, this holds independently of the underlying source of fluctuations in the economy, stressing the role of the nominal exchange rate regime per se in affecting the variability of the real exchange rate. However, only a model featuring incomplete exchange rate pass-through can account for a broader range of exchange rate statistics. Finally there exist ranges of values for either the degree of openness or the elasticity of substitution between domestic and foreign goods for which the baseline model is also consistent with the empirical insensitivity of output volatility to the type of exchange rate regime, as documented by Baxter and Stockman [Journal of Monetary Economics 23 (1989) 377].     

The economic effects of the 1920 eight-hour working day reform in Sweden

In 1920, the working day in Swedish manufacturing and services was cut from 10 to 8 hours without wages being cut correspondingly. Since workers demanded and got the same daily wage working 8 hours as they had with 10, real hourly wages increased dramatically; they were about 50% higher in 1921–1922 than they had been in 1919. This is the largest wage push in Swedish history, and this paper studies the consequences for profits, investments, capital intensity and unemployment. In traded manufacturing employers responded by increasing capital intensity and did not compensate for rising wages by raising prices, which led to a combination of jobless growth and low profit rates in the 1920s. Firms in non-traded manufacturing and services could raise prices and conserve profitability to a higher degree. In total, the effects of the reform were pro-labour. We discuss the implications for our understanding of interwar wages and employment, the literature on the decrease in inequality found in most industrial countries around 1920 and the rise of the ‘Swedish model’ in the 1920s and 1930s.     

Migration and imperfect labor markets: Theory and cross-country evidence from Denmark,Germany and the UK

We investigate the labor market effects of immigration in Denmark, Germany and the UK, three countries which are characterized by considerable differences in labor market institutions and welfare states. Institutions such as collective bargaining, minimum wages, employment protection and unemployment benefits affect the way in which wages respond to labor supply shocks, and, hence, the labor market effects of immigration. We employ a wage-setting approach which assumes that wages decline with the unemployment rate, albeit imperfectly. We find that the wage and employment effects of immigration depend on wage flexibility and the composition of the labor supply shock. In Germany immigration involves only moderate wage, but large unemployment effects, since immigrants are concentrated in labor market segments with low wage flexibility. The reverse is true for the UK and Denmark.     

Fiscal stimulus and the role of wage rigidity

In this paper we study the impact of an expansion in public spending in an economy characterized by limited asset market participation and sticky wages. The flexible wage version of the model implies strong expansionary effects on output and consumption but also a counterfactual increase in real wages. The introduction of sticky wages, besides being a realistic addition, solves this problem and preserves the expansionary effects on output and consumption. Moreover, once we introduce segmentation in the labor market, sticky wages are even essential to obtain expansionary effects.
