EXPERIENCE OF PRIVATIZATION IN EASTERN GERMANY*

ABSTRACT^**: The analysis of the experience of privatization in Eastern Germany shows that the boundaries between the private and public sectors will become increasingly blurred, with the public sector becoming more like the private sector. One may also expect that employment will fall and productivity greatly increase. The legislature's urge to regulate everything will ultimately subside but the public sector will continue to be of vital importance for the economy as a whole. A modernized public sector will be able to deploy its services to make an important contribution to economic growth and employment.     

Effects of Public Infrastructure on Cost Structure and Productivity in the Private Sector

This paper examines the effects of public infrastructure on the cost structure and productivity in the private sector in Australia. Translog cost functions incorporating public capital infrastructure are estimated for the aggregate private sector as well as for seven broad industry groups using annual time series data for 1968/69–1995/96. The effects of public infrastructure on productivity are measured in terms of both cost-saving and output-augmenting measures. The empirical results suggest that public infrastructure has a positive and significant impact on productivity in private sector industries. Public capital serves as a substitute for both private capital and labour. The rates of return to public capital are significant and vary over the sample period.     

Public Investment Rules and Endogenous Growth with Empirical Evidence From Canada

This paper examines theoretically and empirically the effects of public investmentrules on output growth in an economy with private and public capital. It is shownthat the decisions on public capital formation are closely associated with the growthrate of output and generate endogenous growth. A permanent change in the policyrule implies a new long-run growth rate of output, but the economy will onlygradually approach the new steady-state due to adjustment costs in private capitalaccumulation. The model predictions are tested using data from Canada for theperiod 1955-1999. The data support the endogenous growth hypothesis and thetwo central assumptions of the model: (i) the growth rate of output follows closelythe rate of infrastructure formation and (ii) private capital formation also followsthe rate of infrastructure formation but adjusts with a delay.     

A comparative analysis of funding schemes for public infrastructure spending in Quebec

The economic literature has been investigating the positive relation between public infrastructure spending and the productivity of the private sector since Munnell (1992). We have introduced this relationship into a recursive dynamic computable general equilibrium model of the Quebec economy to investigate various funding schemes to scale up infrastructure spending in the province. We draw our assumptions from Estache et al. (2010) combined with sectoral elasticity parameters. We conduct a comparative analysis where the funding comes from debt alone, and debt with sales tax, income tax and business tax. Our main finding is that the income tax seems to produce the most positive effects and the businesses tax the most negative effects, though differences are small.     

The sustainability of economic transformation

The paper analyzes the feasibility of sustaining both macroeconomic stability and political support during economic transformation. Macroeconomic stability requires that state sector losses plus public infrastructure investment be financed by tax revenue plus any external assistance. Political sustainability depends on the income gains and losses experienced by three groups—state sector workers, private sector workers, and private savers/investors. The aggregate income gains from allowing heterogeneous workers to make occupational choices consistent with their comparative advantages can outweigh or significantly offset the short-run economic efficiency costs of maintaining political support for the transformation. Successful transformation may depend on external assistance, but this need will diminish over time.     

Infrastructure investment and Canadian manufacturing productivity

This paper examines the relationship between Canadian public infrastructure and private output using a Constant Elasticity and Substitution-Translog (CES-TL) cost model to describe the interaction of the public and private sectors.

We find public capital a substitute for private capital within the Canadian manufacturing sector. Additionally, the services of public capital enhance the productivity of private capital. Canadian manufacturing costs are characterized by economies of scale, indicating that less than optimal plant sizes dominated Canadian manufacturing sector during the study period. Advances in disembodied technical progress are also indicated.     

The economics of crowd out under mixed public/private health insurance

It is well known that public insurance sometimes crowds out private insurance. Yet, the economic theory of crowd out has remained unstudied. Here, I show that crowd out causes two countervailing effects: (a) the intensive margin effect-since high demanders are crowded out, the private market now has a larger proportion of low demanders on the intensive margin (The intensive margin are those who have already bought private insurance), and so will drop quality to lower the price to the low demanders liking; and (b) the extensive margin effect-before the public insurance expansion, the private sector had lowered quality to make insurance more affordable at the extensive margin (The extensive margin is the next group of people who would buy private insurance if the price decreased), but now that public insurance crowds out the extensive margin, quality can then be raised back up to the high demanders liking.If the extensive margin effect dominates, then a new phenomenon of push out occurs, in which crowd out causes the private sector to raise quality and to increase the number of uninsured low demanders not eligible for public insurance. If the intensive margin effect dominates, then crowd out will cause the private sector to lower quality, causing the phenomenon of crowd-in, in which the number of uninsured low demanders that take-up private insurance increases.These two countervailing effects have important implications for any government policy that desires to eradicate all uninsurance. First, if push out is dominant, then the private sector will respond to the public insurance by pushing out and leaving some people newly uninsured. If crowd-in is dominant, then all people can be insured and the government can do it at a lower-than-anticipated level of expansion due to the private sector crowding in.Received: April 2002, Accepted: February 2003, JEL Classification: I11, I38The views herein do not necessarily reflect the views or policies of AHRQ, nor the U.S. Department of Health and Human Services.

UNDERSTANDING THE RELATIONSHIP BETWEEN INFRASTRUCTURE PUBLIC‒PRIVATE PARTNERSHIPS AND INNOVATION

While the contemporary academic discourse regards innovation as an inherent feature of infrastructure public?private partnerships (PPPs), the conceptual link between infrastructure PPPs and innovation is narrowly understood. While most existing studies conceptualize the innovation processes and effects within the context of PPP projects, we argue that the relevance of innovation in infrastructure PPPs goes beyond specific projects. In this conceptual article, we examine why and how infrastructure PPP innovations can shape the evolution of the involved private and public sector organizations – and therefore the respective sectors – more broadly. We show that innovation in the context of PPPs has much broader implications and potential outcomes than as emphasized in the literature so far.     

Philippine Infrastructure and Connectivity: Challenges and Reforms

The Philippines has performed creditably well in the past few years. Ensuring better infrastructure and connectivity is crucial in attaining inclusive growth. This will require substantial investments in infrastructure. Various reforms to address the infrastructure lack were implemented but there is scope for more reforms: improving fiscal space, reforming budgetary processes, improving public‐private partnerships (PPPs) and the regulatory environment, and better policy coordination to address problems of connectivity and infrastructure. The Philippines has to continuously improve the governance framework, ensure stability and predictability of policies and regulations. Better coordination among a diverse set of governmental infrastructure bodies, and also between government and the private sector is needed to address infrastructure bottlenecks.     

Modelling the dynamics of corruption and unemployment with heterogeneous labour

This paper presents an endogenous growth model with heterogeneous labour, endogenous unemployment, and public sector corruption. Unlike most previous studies, the model does not separate public officials and private individuals into two distinct groups. Instead, taking up bureaucratic appointment as a public servant is modelled as an occupational choice, which then allows for the endogenous determination of the proportion of public officials, the share of corrupt officials among them, and the public investment efficiency of the economy. The dynamics of endogenous corruption and unemployment are studied using numerical policy experiments based on a stylized representation of a middle-income African economy with high corruption and unemployment. The main finding is that, large-scale public infrastructure push has no effect on raising growth in an economy with high corruption. However, if preceded by social and anti-corruption policies that successfully induce a structural change, it will then be effective in raising growth.     

Market Reform and Infrastructure Development in Transition Economies

This paper analyzes the determinants of investments in physical infrastructure over the first decade of market reform in Central and Eastern Europe and other former Soviet economies. Both market and political reform would be expected to have an impact on the level of infrastructure, but the relationship will likely differ for infrastructure which remains dependent on the public sector and that which becomes more dependent on private investment after such reforms. Results for a large cross section of transition economies show that market reform has had a positive impact on both traditional and newer types of infrastructure, with a stronger impact on the newer types which are more likely to be market‐derived. The findings also suggest that market reform is more likely to push investors to develop infrastructure when political and market reforms are accomplished in tandem.     

The impact of public capital on the US private economy: new evidence and analysis

This paper presents new evidence on the impact of public capital on the productivity of the US private sector. Using a production function approach, we estimate the impact of public investment on private capital productivity, specifically addressing the empirical critiques of earlier studies. We find evidence of a cointegrating relationship in a dynamic specification of an empirical model that includes public infrastructure as a factor of production, indicating the existence of a long‐run relationship between the US public capital stock and the productivity of the private capital stock. The results are used to explore how the decline in the growth rate of the public capital stock would have affected the performance of the private sector.     

THE DIVERSITY GAP IN THE PUBLIC–PRIVATE PARTNERSHIP INDUSTRY: AN EXAMINATION OF WOMEN AND VISIBLE MINORITIES IN SENIOR LEADERSHIP POSITIONS

Despite intense focus on leadership diversity in industries such as high technology, business, the media and academia, to date the infrastructure sector has not received the same level of scrutiny. This paper develops a theoretical framework to explain why leadership diversity matters in the management of complex infrastructure projects delivered through public – private partnerships, and then empirically identifies the diversity gap in senior leadership in the PPP industry worldwide. The study is based on an examination of over 2,800 public and private sector executives, board members and politicians responsible for PPPs in over 90 countries. The results show that women and racial minorities are significantly underrepresented in senior leadership roles, a pattern that is deeply entrenched and consistent globally. The paper concludes by discussing the implications of the findings for the infrastructure industry, and explores how a lack of leadership diversity can influence project management outcomes.     

Getting help from abroad: The macroeconomics of foreign direct investment in infrastructure in low‐income countries

Infrastructure financing needs in most low‐income countries are substantial, but funding for such needs is only partly covered by national governments and aid donors. This paper introduces foreign direct investment (FDI) through public–private partnerships as a source of infrastructure financing in low‐income countries. A two‐sector open economy model is developed to assess the macroeconomic performance of FDI in infrastructure. With efficient foreign investment, an increase in revenue‐generating infrastructure investment boosts productivity and spurs private investment while stabilizing domestic prices. A direct comparison between infrastructure financed by domestic versus foreign investment shows that foreign investment creates higher output growth and welfare gains and is preferable to domestically sourced investment, irrespective of the underlying financing instrument the domestic economy is employing. FDI in non‐revenue‐generating infrastructure is also analyzed and discussed.     

Should mobile capital pay for public infrastructure investment?

The paper contributes to the discussion of fiscal competition with infrastructure goods. We explicitly focus on the costs of providing public infrastructure capital that appear in the public budget as investment. Thus we analyse the problem in a dynamic framework. Public infrastructure is considered as a marginal product complement to private capital. A central result of the model is that the fact that public capital is a complement to private capital, so that an increase in the supply of public capital ceteris paribus improves the marginal productivity of private capital, cannot be used as an argument to support a source tax. The so-called indirect productivity effect on private capital induced by public inputs does not justify the taxation of mobile capital. Rather, the efficiency of a source tax on mobile capital income depends on the question of whether or not the public input generates a factor rent to private capital.

Factor‐biased public infrastructure and wage inequality

This paper analyzes how factor‐biased public infrastructure affects the skilled–unskilled wage inequality. In the basic model with a full employment economy, we find that when the weighted dependence of skilled labor and capital in the urban skilled sector on public infrastructure is large enough relatively to that of unskilled labor and capital in the urban unskilled sector, the wage inequality will be expanded. We also discuss labor‐biased and capital‐biased public infrastructure in our framework, and find that the relative dependences of relevant labor or capital on public infrastructure are important determinants of wage inequality. In the extended models, we analyze separately the issue of wage inequality in the economy with unemployment and the totally open capital market, and find the results of the basic model almost still hold.     

Post-Lange Market Socialism: An Evaluation of Profit-Oriented Proposals

In recent years we have observed significant growth in the private sector in many higher education systems around the globe. This growth of private higher education is associated with high political expectations, notably concerning greater choice of programs and greater responsiveness of institutions to students' and labor markets' demands. Looking at the experience of several European and Latin American countries, this study analyzes the patterns of program diversification of public and private higher education and discusses the impact of the private sector for the diversification of higher education's supply. The results show a contrasting picture between political beliefs about privatization in higher education and its actual results, suggesting that private institutions tend to be far more specialized than their public counterparts.     

Labour market effects of public capital stock: evidence for the Spanish private sector

This paper provides a new rationale for the positive effect of public capital stock on employment and wages. We show that higher levels of public capital reduce wages along the wage equation and enhance employment due to the resulting larger elasticity of labour demand with respect to wages. The estimation of a structural model for the Spanish private sector reveals that this wage channel is empirically relevant. We use the estimated parameters to simulate the recent incidence of the ratio of public to private capital stock on the private sector economic performance. We find (i) sizeable effects on employment, capital stock and gross domestic product, and (ii) that the wage channel is particularly important for employment.
