Structural Change,Expanding Informality and Labor Productivity Growth in Russia

Strong growth, intensive structural change, and expanding informality have characterized many developing and emerging economies in recent decades. Yet most empirical investigations into the relationship between structural change and productivity growth overlook informality. This paper includes the informal sector in an analysis of the effects of structural changes in the Russian economy on aggregate labor productivity growth. Using a newly developed dataset for 34 industries covering the period 1995–2012 and applying three alternative approaches, aggregate labor productivity growth is decomposed into intra-industry and inter-industry contributions. All three approaches show that the overall contribution of structural change is growth enhancing, significant, and decreasing over time. Labor reallocation from the formal sector to the informal sector tends to reduce growth through the extension of informal activities with low productivity levels. Sectoral labor reallocation effects are found to be highly sensitive to the methods applied.     

A structural event study for M&As: an application in corporate governance

We apply structural event study methodology in the context of corporate governance to account for the interaction of two merger and acquisition (M&A) effects: synergy (total value) and dominance (bargaining power). The interaction of these effects simultaneously determines the parties’ abnormal returns. We posit that M&A synergy effects correspond to changes in agency costs between target’s management and target’s shareholders, while the dominance effects correspond to the balance of power between acquirer and target during negotiations. Our structural estimates suggest that more stable or entrenched directors generate higher value during normal operations but are softer negotiators when their firm becomes an acquisition target.     

Macroeconomic effects of fiscal policy changes: A case of South Africa

This study develops comprehensive full-sector macro-econometric models for the South African economy with the aim of explaining and providing the macroeconomic effects of fiscal policy changes in the country. The models are applied to test the effectiveness of fiscal policy actions in an economic environment with existing structural supply constraints versus demand-side constraints and also to detect which components of the fiscal would be more effective in stabilising the economy. Based on the structure of the South African economy and the framework presented, the study concludes that the South African economy can be characterised as one which is embedded with structural supply constraints. Thus, a model which is suitable for policy analyses of the South African economy needs to capture the long-run supply-side characteristics of the economy. A price block is incorporated to specify the price adjustment between the supply-side sector and real aggregate demand sector. The models are estimated with time-series data from 1970 to 2011, capturing both the long-run and short-run dynamic properties of the economy. The results from the series of fiscal policy scenarios suggest that fiscal policy actions are more effective in an economic environment with limited or no supply constraints. Fiscal expansion or consolidation that comes more from government spending changes will be more effective in an economic environment where structural supply constraints are absent while tax revenue changes will be more effective in an economic environment where there exist major structural supply constraints.

The impact of productivity and demand shocks on structural dynamics: Evidence from Austrian manufacturing

Based on Pasinetti's model of structural dynamics we develop an empirical identification strategy for aggregate and sectoral labor productivity and demand shocks in a structural vector autoregressive model with long-run restrictions. Impulse response analysis shows that we can distinguish four patterns of the effects of changes in demand and productivity growth on sectoral output growth. For some industries demand is indeed the factor driving sectoral growth. Labor productivity and demand shocks are closely associated with the growth rates of employment and output across industries. However, there is less correlation with entry and exit. This suggest that structural change within and between industries may have quite different determinants.     

Hysteresis versus natural rate in Taiwan's unemployment: Evidence from the educational attainment categories

This study examines the hysteresis hypothesis in unemployment for Taiwan's educational attainment categories. Both nonlinear dynamics and structural breaks in unemployment are applied in our examinations. The empirical results without structural changes show that the unemployment hysteresis hypothesis cannot be rejected in all educational attainment categories. After simultaneously incorporating nonlinear processes and smooth structural changes, we find that only the unemployment rate of junior college graduates reveals a mean reverting to the natural rate in the long-run, whereas all other series still support the hysteresis hypothesis. The results indicate that: i) the shocks have only temporary effects on the unemployment rate of the junior college graduates; ii) the labor or macroeconomic stabilization policies could have long lasting effects on unemployment rates of the other educational attainment categories; iii) the unemployment rates of low-skill labor are susceptible to the changes of economic or fiscal policies; and iv) practical and occupational training mechanisms should be implemented and strengthened in the higher education system to alleviate the increasingly serious problem of unemployment.     

产业结构变动、技术进步与低碳经济发展:以广东省为例

本文基于碳排放强度的视角,运用转换份额分析法,将结构变动和技术进步从碳排放强度变化率中分解出来,实证度量了广东省产业结构变动和技术进步对低碳经济发展的影响。结果表明:1999年以来技术进步是决定广东省碳排放强度变化的关键因素,而产业结构变动对碳排放强度变化的影响作用较小;从产业部门看,工业部门对整体经济碳排放强度变化的作用最大。因此,在优化产业行业结构中,支持重点产业行业的节能减排技术进步,进一步降低二氧化碳排放强度,是广东未来实现低碳经济发展的关键。     

Marketization and Poland's transfer payments

This study will examine the effects of Poland's transition on structural and policy changes in the primary categories of central government transfer payments, family assistance programs, pensions, and unemployment benefits. In this paper, changes in the structure of transfer payments for 1990 through 1997 will be quantified, and the relevant programs are described. This paper also examines the regulatory and policy framework of transfer payments. The welfare effects of transfer payment changes on Poland's different societal groups will be calculated, and certain policy recommendations are presented.     

Unemployment compensation and aggregate fluctuations

This paper focuses on a theoretical and empirical analysis of the effects of discretionary changes of unemployment compensation payments on aggregate fluctuations. By means of a dynamic stochastic general equilibrium model, it is shown that unemployment compensation can stabilize consumption on the one hand; however, on the other one, it has adverse effects on unemployment and output. These theoretical results are confirmed by the empirical structural vector autoregressive model. Moreover, the results highlight the importance of real wages in transmitting unemployment benefit shocks on to the macroeconomy. In particular, discretionary changes lead to an increase in real wages, unemployment and consumption while inducing a small decline in output.     

经济全球化对生态环境的影响

随着世界贸易、投资自由化的逐步扩大和现代科学技术特别是信息技术的发展，经济全球化作为一种新的国际关系正在加快推进全球产业结构调整。关于贸易自由化的环境影响，自由贸易倡导者与环境主义者之间存在着分歧。事实上，贸易全球化对环境的总体影响是规模效应、结构效应、技术效应和产品效应的复杂变化的净结果。跨国公司是经济全球化的载体，有潜力在全球可持续发展中扮演正面角色。在竞争市场中，环境保护是跨国公司的一个重要考虑，但是以经济增长来为顾客和股东服务仍然是跨国公司的中心任务。跨国公司的环境管理实践应把可持续发展作为生存公式。     

A modified procedure for simulation of macroeconometric models

The rational expectations literature suggests that even the effects of unanticipated changes in policy variables may not be accurately described by conventionalsimulations of macroeconometric models. Beginning with Zellner and Palm's time-series approach to structural econometric modelling, a modified simulation procedure is developed to examine the effects of changes in policy variables which are consistent with historic time-series processes. A state-space representation and the Akaike Information Criterion are used to model exogenous variable processes, and results from modified and conventional simulations are compared.     

Trend-cycle decomposition allowing for multiple smooth structural changes in the trend of US real GDP

A key feature of Flexible Fourier Form (FFF) is that the essential characteristics of multiple structural changes can be captured using a small number of low frequency components from a Fourier approximation. We introduce a variant of the FFF into the trend function of US real GDP in order to allow for gradual effects of unknown numbers of structural changes occurring at unknown dates. We find that the hypothesis of no changes can be rejected, and the Fourier components are significant. Our new cycle matches the NBER chronology very well, especially for the Great Recession of 2009.     

The impact of federal funds target changes on interest rate volatility

This paper empirically investigates the 1-day response of interest rate volatility to a federal funds target rate change over the period 1989–2003. Federal funds futures data are used to distinguish between anticipated and unanticipated changes in the funds rate target. Interest rate volatility is modeled as an EGARCH process. The volatility response to an unanticipated Fed policy action is relatively large in size and highly significant for short-term interest rates. However, interest rates at long maturities are found to be responsive to target rate changes, even if they are anticipated, when estimations take into account of structural change in association with the Fed's policy disclosure beginning in 1994, as well as asymmetrical effects between monetary easing and tightening.     

Direct effects of money on aggregate demand: another look at the evidence

Now that a number of central banks are faced with short-term nominal interest rates close to or at the zero lower bound, there is a renewed interest in the long-running debate about whether or not changes in the stock of money have direct effects. In particular, do changes in money have additional effects on aggregate demand outside of those induced by changes in short-term nominal interest rates? This article revisits and reinterprets the empirical evidence based on single equation regressions which is quite mixed, with some results supporting and other results denying the existence of direct effects. We use a structural model with no direct effects of money to show that the finding of positive and statistically significant coefficients on real money growth can be misleading. The model generates data that, when used to estimate analogues of the empirical regressions, produce positive and statistically significant coefficients on real money growth, similar to those often found when using actual data. The problem is that single equation regressions leave out a set of variables, which in turn, give rise to an omitted variables bias in the estimated coefficients on real money growth. Hence, they are an unreliable guide to calibrate monetary policies, in general, including at the zero lower bound.     

Does tax policy affect credit spreads? Evidence from the US and UK

This paper studies how exogenous tax changes affect credit market conditions in the US and UK. Using both structural VAR and structural factor-augmented VAR (FAVAR) model, we find that tax-policy shocks have significant effects on the credit spread. Specifically, the credit spread responds first positively and then negatively to an exogenous tax increase in the two countries. Moreover, the impulse responses of the credit spread to tax-policy shocks do not always accord well with the impulse responses of the output. This indicates that there are channels of tax policy transmission to the credit spread other than through its impact on the business cycle.     

Changes in Global Trade Patterns and Women's Employment in Manufacturing, 1995–2011

This study investigates the feminization and defeminization trends in manufacturing employment in thirty countries from 1995 to 2011. Utilizing two separate methods, structural decomposition analysis (SDA) and factor content analysis (FCA), the study identifies the major industries and trade partners behind the structural shifts in trade that have induced changes in employment and thus in the rates of women’s employment. The findings highlight that, as a general trend, defeminization in manufacturing has persisted in the Global North, led by a negative trade impact in low-technology industries. In the Global South, feminization and defeminization trends are not as straightforward. Despite positive changes in women’s share of employment in medium-high- and high-technology industries, negative gender bias effects of trade changes are found particularly in high-technology industries, where occupations are notably gendered.     

The UK economy in the late 1980s: trends and prospects

The British economy in the 1980s has been characterized by structural changes which, in their scale and rapidity, are in many ways unprecedented. Moreover further change is in store, since the impending decline of North Sea oil output will have significant effects on Britian's external position, and possibly on public finance. This paper (a) reviews past and prospective structural changes, partiularly in terms of their effects on the balance of payments, (b) outlines and critically discusses the government's view of the situation and its development, (c) discusses some likely adjustment problems over the medium term, and (d) considers the options and constraints for policy in the late 1980s and early 1990s.

The limits of the welfare state

The purpose of this paper is to discuss the links between the welfare state and economic development using Swedish data between 1970 and 1995. Our main arguments are that political decisions give rise to long-term structural changes in welfare that do not follow structural changes in the economy. Changes in the business cycle may strengthen or weaken these long-term effects. The main results point to the rising problem that face a society with a high degree of labor participation, universal coverage in social insurance, and a relatively low growth rate. There is a hidden labor market problem in social insurance. The redistribution policy is based on a short-run perspective affecting long-run effects negatively. The process in political decision may be considered as a source of government failure.
