Autoverkopen en autopark in Nederland, 1950–1970

Summary This is a study of the demand for the ownership of new or firsthand cars, i.e. the demand of ‘first owners’ who habitually buy new cars which are then traded in long before they are obsolescent. Upon combining the evidence of various surveys with time-series for 1950-64 it is found that this ownership has an income elasticity of 2 and a price elasticity of – 1.25 in respect of the constant-quality index of new car prices earlier provided. On the average new cars are traded in after three years so that roughly one third of the existing stock is replaced every year. These values together determine an equation for purchases of new cars which accurately predicts new registrations in 1965 and 1966. Projections for the years 1967-70 are provided. In the model employed the total number of cars (including used cars) is determined by the active demand exerted by ‘first owners’ on one hand and by the hitherto fairly constant scrappage rates on the other. Projections of the overall ownership rate can therefore be derived from the forecasts of new registrations. The ownership rate will approach 80% around 1970, and it is likely that at that stage the current scrappage rates will cease to apply in view of the greater predilection for comparatively younger cars.     

Optimale rantsoenering van aardolie en aardolieprodukten in Nederland; een toepassing van input-outputanalyse en lineaire programmering

Samenvatting Bij een invoerrestrictie van ruwe olie ontstaat het probleem van de optimale verdeling van de olie over de verschillende bedrijfstakken. Met behulp van input-outputanalyse kan dit probleem worden getransformeerd in een lineair-prograrnmeringsvraagstuk. In het navolgende artikel worden een aantal oplossingen gepresenteerd die men verkrijgt bij verschillende veronderstellingen omtrent bezuinigingsmogelijkheden, verbruiksminima enz.     

Ethnic Competition for Residential Space in Miami, Florida, 1970–80

A bstract . Between 1970 and 1980 the Hispanic population of Miami had a phenomenal rate of growth while the Black population also grew rapidly. The non-Hispanic White population actually experienced a numerical decline. The Hispanic population of the city has been highly successful in improving its economic well-being and has been able to penetrate deeply into non-Hispanic White neighborhoods throughout the city. Blacks have not been able to increase their economic well-being as greatly and their expansion has been confined largely to neighborhoods adjacent to older Black neighborhoods. Non-Hispanic White neighborhoods shrank considerably in area during the decade and today are mainly found on Miami Beach , in northeast Miami and the far south of the city. If large scale Hispanic migration continues, and the Black population maintains its rate of growth, by 1990 Miami will likely have an even smaller non-Hispanic White population than today and be ethnically more segregated.     

Leapfrogging, Urban Sprawl, and Growth Management: Phoenix, 1950–2000

Through a case study of Phoenix, Arizona, this paper examines how urban sprawl is linked to opportunities for capital gains. It focuses on leapfrogging, in which developers skip over properties to obtain land at a lower price further out despite the existence of utilities and other infrastructure that could serve the bypassed parcels. The paper examines patterns of growth since 1950 and planners' efforts to structure that growth. It discusses two programs that addressed consequences of leapfrogging: development impact fees to help pay for infrastructure costs of new development and an Infill Housing Program to encourage residential development on vacant land. It concludes with a brief discussion of the future of growth management in Phoenix.     

Markets, Culture and Institutions: The Emergence of Large Business Groups in Taiwan, 1950s–1970s

Business groups are a special type of enterprise system existing in almost every market economy. Member firms do not operate as isolated units in the markets but have institutionalized relationships with each other and work coherently as an entity. Groups play a central role in economies in which they operate. For Taiwan, the largest 100 groups produced one third of the GNP in the past 20 years. Why does this organizational form exist in the first place? This paper reviews three relevant theories, market‐centred theories, culturalist perspective, and the institutional approach, and employs the data of 150 Taiwanese groups for the answer. The market‐centred theories and the institutional arguments are examined statistically and the latter is supported by the data. Following this evidence, the Boolean comparison of group firms with non‐group firms confirms that lacking a coherent core in ownership and management makes firms unable to respond to institutional incentives promptly. Finally, the structure of family ownership network in business groups refutes the cultural perspective which argues that the equal inheritance pattern of family property drives entrepreneurs to establish separate firms rather than single hierarchies. While both markets and culture play a distinct part in the story, it is regulatory institutions that lead to group formation.     

The Effectiveness of Public Assistance Payments (1970–80) in Reducing Poverty Reconsidered

A bstract . The effectiveness of public assistance in reducing poverty in the U.S.A. is re-examined by estimating the extent of public assistance among all families and of families officially defined in poverty. Also studied is the extent of public assistance among families not defined as in poverty. The findings are further analyzed for their changes during the decade 1970–80. It is found that errors of commission (assisting families not in poverty) and of omission (not assisting families in poverty) were quite widespread in 1980, although significantly reduced from their high prevalence in 1970.     

House Prices and Housing Investment in Sweden and the UK: Econometric Analysis for the Period 1970–1998

We estimate quarterly dynamic housing demand and investment supply models for Sweden and the UK for the sample period 1970–1998, using an Error Correction Method (ECM). To facilitate comparisons of results between Sweden and the UK we model both countries identically with approximately almost the similar type of exogenous variables. The long–run income elasticities for Sweden and the UK are constrained to be 1.0, respectively. The long–run semi–elasticity for interest rates are 2.1 and 0.9 for Sweden and the UK. The speed of adjustment on the demand side is 0.12 and 0.23, while on the supply side it is 0.06 and 0.48 for Sweden and the UK, respectively. Granger causality tests indicate that income Granger causes house prices for Sweden, while for the UK there is also feedback from house prices to income. House prices Granger cause financial wealth for Sweden, while for the UK it is vice–versa. House prices cause household debt for Sweden, while for the UK there is a feedback from debt. Interest rates Granger cause house prices for the UK and Sweden. In both countries Tobin's q Granger cause housing investment. Generally, the diagnostic tests indicate that the model specifications were satisfactory to the unknown data generating process.     

Problems in Acquiring Mineral Revenues for Financing Economic Development: A Case Study of Zambia During 1970–78

A bstract . During the 1970s Zambia granted tax incentives to transnational mining companies (thereby foregoing some revenue ) in order to achieve expected investment benefits to the economy and government. The Government also acquired ownership interests in the companies via asset acquisition. Global market forces turned against Zambia's interests, and expected benefits were not forthcoming because company profits had become the sole tax base in the mineral sector. Zambia's experience from 1970 to 1978 suggests that it and other mineral export countries should (a) evaluate carefully whether reducing the effective tax rate on company profits actually induces investment , and (b) consider thoroughly whether a tax scheme that includes a proper mix of profit, mineral and export levies is more appropriate than a single tax base.     

Strikes and strike trends in West Germany, 1950–78

During the 1970s West German social scientists began to pay more attention to the strike phenomenon. In this article the author reviews recent research contributions in the Federal Republic and analyses the quantitative and qualitative aspects of strikes over the last thirty years.     

House Price Dynamics in Mumbai, 1989–1995

The objective of this paper is to study the importance of price index methodology to analyzing intra-metropolitan house price variations in Mumbai. Two hedonic regression-based approaches – cross section and explicit time variable – are compared. The results indicate conclusively that the former is better than the latter. This paper also contributes to the literature on intra-metropolitan house price variations by explaining them based on urban development, population and employment patterns in Mumbai.
