The baby boom,the baby bust,and the housing market

This paper explores the impact of demographic changes on the housing market in the US, 1st by reviewing the facts about the Baby Boom, 2nd by linking age and housing demand using census data for 1970 and 1980, 3rd by computing the effect of demand on price of housing and on the quantity of residential capital, and last by constructing a theoretical model to plot the predictability of the jump in demand caused by the Baby Boom. The Baby Boom in the U.S. lasted from 1946-1964, with a peak in 1957 when 4.3 million babies were born. In 1980 19.7% of the population were aged 20-30, compared to 13.3% in 1960. Demand for housing was modeled for a given household from census data, resulting in the finding that demand rises sharply at age 20-30, then declines after age 40 by 1% per year. Thus between 1970 and 1980 the real value of housing for an adult at any given age jumped 50%, while the real disposable personal income per capita rose 22%. The structure of demand is such that the swelling in the rate of growth in housing demand peaked in 1980, with a rate of 1.66% per year. Housing demand and real price of housing were highly correlated and inelastic. If this relationship holds in the future, the real price of housing should fall about 3% per year, or 47% by 2007. The theoretical model, a variation of the Poterba model, ignoring inflation and taxation, suggests that fluctuations in prices caused by changes in demand are not foreseen by the market, even though they are predictable in principle 20 years in advance. As the effects of falling housing prices become apparent, there may be a potential for economic instability, but people may be induced to save more because their homes will no longer provide the funds for retirement.     

The baby boom and the housing market: Another look at the evidence

Based on tests for cointegration, the growth of housing demand resulting from the Baby Boom appears to be the major factor behind increased real residential investment, but not the major factor behind increased real housing prices in the postwar U.S. The housing market also passes a simple test for efficiency.     

The baby boom, the baby bust, and the housing market A second look

I re-examine Mankiw-Weil's (MW) claim that house prices will fall 47% by 2007. MW argue that the arrival of the Baby Boom generation at adulthood drove up prices during the 1970s. When the beginnings of the Baby Bust generation matured in the 1980s, prices softened. When this generation arrives in earnest, prices will collapse. I make three points: (1) The regression upon which MW hang their prediction has an implausible -8.1% trend, which drives their prediction. (2) Demand directly influences the rental price; the asset price (MW's variable) is influenced by demand only indirectly. I re-run MW's regression, replacing the asset price with the rental price, and their prediction disappears. (3) Relying on data presented by MW, I show that housing consumption rose during the 1970s, after adjusting for income growth. Just when MW say the asset price of housing was rising, consumers behaved as if the price were falling. Consumers were right: The rental price fell by approximately 20% during the 1970s.     

The price responsiveness of housing supply in OECD countries

The responsiveness of housing supply to changes in prices bears important implications for the evolution of housing prices and the speed of adjustment of housing markets. Based on a stock-flow model of the housing market estimated within an error correction framework, this paper estimates the long-run price elasticity of new housing supply in 21 OECD countries. Estimates suggest that the responsiveness of housing supply to price changes varies substantially across countries. It is relatively more flexible in North America and some Nordic countries, while it is more rigid in continental European countries and in the United Kingdom. The responsiveness of housing supply depends not only on national geographical and urban characteristics but also on policies, such as land use and planning regulations.     

Disaggregate productivity comparisons: sectoral convergence in OECD countries

International comparisons of productivity have used exchange rates or purchasing power parity (PPP) to make output comparable across countries. While aggregate PPP holds well in the long run, sectoral deviations are persistent. It raises the need for a currency conversion factor at the same level of aggregation as the output that is compared. Mapping prices from household expenditure surveys into the industrial classification of sectors and adjusting for taxes and international trade, I obtain an expenditure-based sector-specific PPP. Using detailed price data for up to 8 years between 1970 and 1999, I test whether the sectoral PPPs adequately capture differential changes in relative prices between countries. They work well for agriculture and the majority of industrial sectors, but not for most service sectors and for manufacturing sectors that produce differentiated products. Using the most appropriate conversion factor for each industry, productivity convergence is found to be taking place in all but a few industries for a group of 14 OECD countries. The latter results are robust to the base year used for the currency conversion.     

Productivity, convergence and policy: a study of OECD countries and industries

This paper analyses trends in labour productivity and its underlying determinants in a panel of OECD countries from 1979 to 2002. Data Envelopment Analysis (DEA) is used to estimate a Malmquist measure of multifactor productivity (MFP) change. We decompose the growth in labour productivity into (i) net technological change (ii) input biased technical change (IBTC) (iii) efficiency change and (iv) capital accumulation. We analyse the effect of each of these factors in the transition towards the equilibrium growth paths of both labour productivity and per capita GDP for the OECD countries, controlling for the effects of different policies and institutions. The results indicate that on average gaps in productivity or income levels are narrowing down although there is no evidence to suggest that the entire OECD area comprises a single convergence “club”. Using kernel estimation methods we find that that labour productivity and per capita GDP are settling toward a twin peak (bimodal) distribution. Panel unit root tests over an extended (1960–2001) period provide general support for the convergence hypothesis. Analysis of the contributions of productivity growth within industries and sectoral composition changes show that aggregate productivity change is predominantly driven by ‘net’ within sector effects with very little contribution emerging from sectoral shifts (the ‘in-between’ static or dynamic effects resulting from higher or above average productivity industries gaining employment shares or low productivity industries losing shares).     

The public–private pension mix in OECD countries

This article provides a survey of selected aspects of the relationship between public and private pension provision in European countries in the Organisation for Economic Co‐operation and Development and compares this with other regions of the OECD. Population ageing has led many OECD countries to undertake a wide range of pension reforms. The overall effect of these reforms has in many cases been to significantly reduce public pension promises. This, in turn, has increased the interest in the role of private pensions, which has expanded significantly in a number of OECD countries. The article discusses the extent to which a number of countries will need to further increase private provision in order to guarantee adequate future retirement incomes.

The eurozone crisis,German hegemony and labour market reform in the GIPS countries

This article argues that the eurozone crisis has led to Germany hegemony, a feature of which has been complete resistance to a genuinely European solution to the crisis. German political leaders have sought to make the eurozone a more stable currency area by demanding far reaching labour market adjustment in the debtor countries of Greece, Ireland, Portugal and Spain, GIPS countries. This article assesses why Germany's leaders elected to act as a coercive hegemon and examines the labour market reform pathways being travelled by GIPS countries. It argues that the austerity regime enacted under German hegemony has obliged the GIPS countries to introduce important labour market reforms. However, these reforms have not threatened the integrity of established national systems of industrial relations. As a result a Euro war of attrition has opened up between the European core and periphery.     

Fiscal decentralization and public sector efficiency: evidence from OECD countries

This paper studies the impact of fiscal decentralization on public sector efficiency (PSE). We first use a theoretical framework that illustrates the two opposing forces that shape a non-monotonic effect of fiscal decentralization on PSE. Subsequently, we carry out an empirical analysis for 21 OECD countries, between 1970 and 2000. A country-level dataset is used to measure PSE in delivering education and health services and the new indices are regressed on well-established decentralization measures. Irrespective of whether PSE concerns education or health services, an inverted U-shaped relationship has been identified between government efficiency in providing these services and fiscal decentralization. This relationship is robust across several different specifications and estimation methods.     

The impact of state power on economic growth rates in OECD countries

Inspired by public choice theories — in particular the work of Bernholz, Downs, Olson and Tullock — two propositions are advanced. First, the older a democracy is, the slower its growth rates should become. Second, the higher the social security spending is, the slower economic growth rates should become. Pooled regression analysis and the growth experience of 19 OECD nations between 1960 and 1985 allow for an empirical test. Unfortunately, results very much depend on a technical issue, i.e., on the inclusion or exclusion of period and country dummy variables. It is argued that inclusion of the dummies is misleading. If you accept these arguments, then the propositions linking age of democracy or social security transfers on the one hand and lower economic growth rates on the other hand are confirmed.     

Measuring a boom and bust: The Sydney housing market 2001–2006

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust.     

Market share and market power in merger and monopolization cases

In light of the growing sophistication of the tools of industrial organization economics and reliance on the federal courts to resolve complicated competitive issues, it may be time for the courts to make greater use of economists in analyzing antitrust cases. While the costs of such an endeavor remain unexplored, we argue below that the benefits may be significant. In particular, we assert that the legal precedent requiring the courts to draw inferences about market power based primarily or exclusively on market shares and/or market concentration¹ can often be misleading. However, the only alternative to such judge-made bright-line rules is to utilize modern economic tools to undertake more extensive competitive analyses. The latter choice is essentially the course that the antitrust enforcement agencies are following. This article explores some of the arguments in favor of such an approach.     

Assessing the efficiency of secondary schools: Evidence from OECD countries participating in PISA 2015

One of the most important issues accompanying the publication of the main results of the well-known Programme for International Student Assessment (PISA) is the classification of countries according to student attainment. However, this ranking does not take into account some highly relevant factors, such as the different resource endowments of each education system or the heterogeneous context in which schools operate. This study aims to provide a fuller picture of education system operation worldwide by assessing the managerial efficiency of secondary schools in a cross-country framework. To do this, we use data from OECD countries participating in PISA 2015 and apply a robust nonparametric approach that accounts for the fact that schools were operating under heterogeneous conditions before the efficiency measures of performance were estimated. Our results suggest that the consideration of both school resources and environmental factors significantly modifies the country ranking based solely on student results.     

The role of insurance growth in economic growth: Fresh evidence from a panel of OECD countries

Insurance is one of the key activities in a globalised financial and economic environment. Through its benefits, it offers income, life and property protection to the insured and their keens, as well as income accumulation that can be used at retirement to help preserve the desired lifestyle or living standards. Motivated by this end of insurance, the goal of this paper is to study the contribution of insurance growth to economic growth, by employing the benefit side of the insurance activity, next to the acquisition side that has already been considered. More precisely, the findings provide evidence that gross claims payments and gross operating expenses are significantly and positively related to economic growth. At the same time, the results confirm the findings of the existing literature that gross premia and insurance penetration are also significantly and positively related to economic growth. The outcomes hold true for total, life and non-life insurance, both during the pre- and post- 2008-crisis periods, even though less strong after the crisis. Furthermore, the positive and statistically significant impact of gross capital formation, government expenditure, secondary schooling, FDI inflows, trade openness and financial development is validated, in line with certain theoretical expectations.     

Efficiency changes in long-term care in OECD countries: A non-parametric Malmquist Index approach

Future demographic projections indicate that long-term care (LTC) demand will put significant pressures on the long-term sustainability of public finances. Efficiency gains could potentially compensate for increasing LTC expenditures. Nevertheless, among the factors that drive LTC expenditures, efficiency, or productivity discussions have received little attention. This paper provides the first analysis of the efficiency levels of LTC for a subset of OECD countries. In doing so, the study adopts a non-parametric approach and performs a Data Envelopment Analysis (DEA). The results of the DEA show that average efficiency scores have a slight tendency to increase. There was a 0.1% increase in productivity in the provision of LTC between 2009 and 2014, which mainly resulted from an increase in technological change. However, the slight increase in efficiency is insufficient to offset fiscal pressures led by the increasing number of LTC beneficiaries and amount spent on LTC. The second stage Tobit analysis results further indicate that the productivity of LTC provision does not differ across countries with different public LTC financing arrangements.     

Cross-sectional differences in the liquidity effects of open market share repurchases

I examine liquidity changes associated with open market share repurchases, with the focus on potential cross-sectional variations of liquidity effects. I hypothesize that a liquidity change, either a decrease or an increase, will be larger in a firm with a higher degree of pre-announcement information asymmetry. Results suggest that the null hypothesis of no liquidity change cannot be rejected. In particular, there is no evidence for cross-sectional variation of liquidity changes across firms with differing degrees of information asymmetry.

Commodity market reform in Africa: some recent experience

Since the early 1980s, dramatic changes in export commodity markets, shocks associated with resulting price declines and changing views on the role of the state have ushered in widespread reforms to agricultural commodity markets in Africa. The reforms significantly reduced government participation in the marketing and pricing of commodities. This paper examines the background, causes, process and consequences of these reforms and derives lessons for successful reforms from experiences in markets for four commodities important to Africa—cocoa, coffee, cotton, and sugar. The commodity focus of the paper highlights the special features associated with these markets that affect the reform process. The paper complements the current literature on market reforms in Africa, where grain market studies are more common. We suggest that the types of market interventions prior to reform are more easily classified by crop than by country. Consequently, there are significant commodity-specific differences in the initial conditions and in the outcomes of reforms related to these markets. However, there are general lessons as well. We find that the key consequences of reform have been significant changes in or emergence of marketing institutions, and a significant shift of political and economic power from public to private sector. In cases where interventions were greatest and reforms most complete, producers have benefited from receiving a larger share of export prices. Additionally, we conclude that the adjustment costs of reform can be reduced in most cases by better understanding the detailed and idiosyncratic relationships between the commodity subsector, private markets, and public services. Finally, while there are significant costs to market-dependent reforms, experiences suggest that they are a necessary step toward a dynamic commodity sector based on private initiative. Indeed, this is particularly true in countries and sectors where interventions were greatest and market-supporting institutions the weakest.
