"Knowledge, technology and economic growth: an OECD perspective"

In this paper we present an international comparison of growth trends with special attention given to developments in labour productivity, allowing for human capital accumulation, and multifactor productivity (MFP), allowing for changes in the composition of fixed capital. In this context an attempt is made, where possible, to identify both the embodied (in particular in ICT equipment) and disembodied components of technical progress. The possible relation between improvements in MFP and the accumulation of knowledge (as proxied by R&D expenditures) is also discussed, and some tentative policy considerations are advanced, mainly with reference to general framework conditions that might have a bearing in fostering technological changes

Do capital gains affect consumption? Estimates of wealth effects from Italian householdsÂ’ behavior

We use detailed data on housing prices in Italy available for a large number of years and with a fine geographical breakdown to compute capital gains and losses on the most widespread asset among consumers, housing, and inquire whether changes in housing values affect consumption. We find that consumer expenditures do react to capital gains, with a marginal propensity to consume out of real value changes of housing wealth of about 0.02. Reactions are different across types of consumers: while homeowners increase consumption when house prices increase, with a marginal propensity of about 0.035, the rentersÂ’ response to the higher house cost tends to be that of increased savings. For the owners of listed stocks the response to capital gains is difficult to estimate with statistical precision, even if, for the limited sample of owners of these assets, its negative sign may be indicative of prevailing substitution over income effects.wealth effects, consumption, housing, stock ownership

The role of macroeconomic policies in the global crisis

This paper argues that the lack of timely and decisive policy action to correct domestic and external imbalances contributed crucially to the build-up of financial excesses that led to the financial crisis and the Great Recession. We focus on 2002-07 and perform a number of counterfactual simulations to investigate two central elements of the story, namely: (a) an over-expansionary US monetary policy and the absence of effective macro-prudential supervision, which permitted a prolonged expansion of debt-financed consumer spending; (b) the decision of China and other emerging countries to pursue an export-led growth strategy supported by pegging their currencies to the US dollar, resulting in a huge build-up of their official reserves, in conjunction with sluggish domestic demand in surplus advanced economies characterized by low potential output growth. The results of the simulations lend support to the view that if substantial, globally coordinated demand rebalancing had been undertaken in a timely manner, the macroeconomic and financial imbalances would not have accumulated to the extent that they did and the financial turmoil might have had less drastic global consequences.global imbalances, financial crisis, monetary policy, macroprudential regulation, structural reforms.

Money, Finance and Demography: The Consequences of Ageing

A significant ageing trend can be observed in Europe and in other parts of the world. Fertility is decreasing and life expectancy increasing. The impact of migration is growing. The book deals with the implications for financial markets of these demographic trends. Leading economists and financial experts from Europe and the United States evaluate the challenges to public pension systems and the private pension industry. Based on long-term projections of productivity and employment they look at potential growth in GDP per capita and implications for savings and wealth. Pension fund portfolio management is discussed together with the ability of capital markets to serve retirement-financing purposes. Fiscal as well as financial sustainability are analysed in depth. The roles of global imbalances and international capital movements are included. Most chapters also discuss policy implications - in particular with regard to how pension saving incentives and rules and incentives for retirement should be in order to ensure fiscal and financial sustainability. All contributions in the book are based on presentations at the 26th SUERF Colloquium on "Money, Finance and Demography - the Consequences of Ageing" held on 12-14 October, 2006 in Lisbon sponsored by Banco de Portugal and Millennium bcp and in cooperation with the Universidade Nova de Lisboa.

Paying for pensions: how important is economic growth?

This paper focuses on the scope for a higher level of output and faster productivitygrowth to ease future fiscal pressures stemming from demographic developments in OECD countries over the next fifty years. After concluding that, without substantial reforms, pressure on government spending linked to ageing populations (both onpensions and health expenditures), will in general result in significant increases in expenditures to GDP ratios, the paper examines how these pressures might be redressed. Responses which focus on achieving an increase in the average number of years individuals spend active in the labour force and raising the level as well as widening the sources of individual provision of retirement income are recommended. Increasing output (through lower structural unemployment and higher female and elderly workers' participation rates) and its rate of growth (through gains in productivity) are seen as offering a complementary, though limited, response
