SEMIPARAMETRIC VECTOR MEM

Financial time series are often non‐negative‐valued (volumes, trades, durations, realized volatility, daily range) and exhibit clustering. When joint dynamics is of interest, the vector multiplicative error model (vMEM; the element‐by‐element product of a vector of conditionally autoregressive scale factors and a multivariate i.i.d. innovation process) is a suitable strategy. Its parameters can be estimated by generalized method of moments, bypassing the problem of specifying a multivariate distribution for the errors. Simulated results show the gains in efficiency relative to an equation‐by‐equation approach. A vMEM on several measures of volatility justifies a joint approach revealing full interdependence.

Forecasting inflation and tracking monetary policy in the euro area: does national information help?

The ECB target is set in terms of the year on year growth rate of the euro area Harmonized Index of Consumer Prices. Nonetheless, a good deal of attention is given to national data by market analysts when they try to anticipate monetary policy moves. In this paper we use the Generalized Dynamic Factor Model to develop a set of core inflation indicators that, combining national data with area wide information, allow us to answer two related questions. The first is whether country specific data actually bear any relevance for the future path of area wide price growth, over and above that already contained in area wide data. The second is whether to track ECB monetary policy decisions it is useful to take into account national information and not only area wide statistics. Within our empirical framework we find that once area wide information is properly taken into account the contribution of national idiosyncratic developments is negligible.     

Does the digital divide matter? The role of information and communication technology in cross-country level and growth estimates

The bulk of information and communication technology is made of weightless, implementable, and infinitely reproducible knowledge products (such as software and databases). These products are transferred by telephone lines, accessed through internet hosts, and processed through personal computers. In this work, the coefficient of the labour augmenting factor in the aggregate production function has been estimated using proxies of variables crucially affecting the diffusion of (non-rival and almost non-excludable) knowledge products. This specification provides interesting answers to some of the open issues in the existing growth literature. The most recent information, though available for a limited period, shows that telephone lines, personal computers, mobile phones, and internet hosts significantly affect levels and growth of income per worker across countries. The result is robust to changes in sample composition, econometric specification, and estimation approach.     

Capturing the real value of patent analysis for R&D strategies

Patent information can be used for strategic planning purposes. Conventional patent analysis has commonly focused on factual information and, in particular, on information extraction, visualisation and interpretation. Less scholarly attention has been devoted to the strategic role of an integrated system of patent intelligence in supporting decision-making in R&D investments. Our paper addresses this gap and explores how patent analysis may benefit those firms that intend capturing the beneficial effects of Open Innovation. We also critically discuss the intrinsic limits of both patent information and patent analysis, which should be taken into account by systems of patent intelligence.     

Provincial business cycles and fiscal policy in China

We characterize the cyclical properties of fiscal policy in China along two related dimensions. First, we estimate the sign and size of the fiscal policy multiplier. Second, we assess whether fiscal policy is conducted pro‐ or counter‐cyclically. To account for the challenges posed by China's vast geography, we use data at the provincial level. We find that (i) fiscal policy generally has ‘Keynesian’ effects, and (ii) fiscal policy is mostly conducted pro‐cyclically. This means that fiscal policy is more an element of destabilization than a tool for stabilization.     

China and Japan: Culture,economics, and geopolitics in the quest for a leading international role

The Western view of China and Japan is often based on a perception that they are both Confucian and, therefore, are more similar than is actually the case. Although both do share some fundamental characteristics of Asian culture, certain unique features of each, particularly at the level of social relationships and cultural landmarks, make them quite different. Analysing what these features are allows us to understand what influence they have on personal choices and on the decisions of leaders on important issues in these countries. The Asian financial crisis of 1997–99 can be taken as a useful acid test for evaluating the different decision‐making capacities of the Chinese and Japanese leaders. Currency devaluation, exchange rate intervention, banking system restructuring, economic reforms, and responses to international pressure were the main areas in which government action took place. Interpreting the decisions made in these areas from a geographical‐cultural perspective provides a solid basis for analysing geopolitical dynamics and the ‘global’ prospects of the two most important nations of the Far East.     

Ageing,cognitive abilities and retirement

We investigate the relationship between ageing, cognitive abilities and retirement using the Survey on Health, Ageing and Retirement in Europe (SHARE), a household panel that offers the possibility of comparing several European countries using nationally representative samples of the population aged 50+. The human capital framework suggests that retirement may cause an increase in cognitive decline, since after retirement individuals lose the market incentive to invest in cognitive repair activities. Our empirical results, based on an instrumental variable strategy to deal with the potential endogeneity of retirement, confirm this key prediction. They also indicate that education plays a fundamental role in explaining heterogeneity in the level of cognitive abilities.     

Competing engines of growth: Innovation and standardization

We study a dynamic general equilibrium model where innovation takes the form of the introduction of new goods whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are adapted to be produced using unskilled labor. Our framework highlights a number of novel results. First, standardization is both an engine of growth and a potential barrier to it. As a result, growth is an inverse U-shaped function of the standardization rate (and of competition). Second, we characterize the growth and welfare maximizing speed of standardization. We show how optimal protection of intellectual property rights affecting the cost of standardization vary with the skill-endowment, the elasticity of substitution between goods and other parameters. Third, we show that, depending on how competition between innovating and standardizing firms is modelled and on parameter values, a new type of multiplicity of equilibria may arise. Finally, we study the implications of our model for the skill premium and we illustrate novel reasons for linking North–South trade to intellectual property rights protection.     

The Making of Pro‐Poor Growth

A system of three endogenous equations is used to estimate the determinants of poverty dynamics. The system incorporates: (i) the direct effect of growth and income inequality on poverty, (ii) the feedback effect of poverty on inequality and growth, and (iii) different channels through which economic policies can contribute to poverty reduction. Results suggest that countries tend to move towards one of two possible equilibria. The positive (virtuous) equilibrium is characterized by fast growth, decreasing inequality, and rapid poverty reduction. The negative (vicious) equilibrium involves slow (or even negative) growth, sharpening inequalities, and resilient poverty. The policy mix is critical in determining to which of the two equilibria a country converges.
