The use of news-based data for tracking the real economy has gained popularity recently as newspapers archives have become accessible and the need for timely information has soared. In this article, on the basis of keyword searches in newspaper articles we construct several versions of the so-called Recession-word Index (RWI) for Germany and Switzerland and exploit its use for forecasting. Our main findings are the following. First, we show that augmenting benchmark autoregressive models with the RWI leads to improvement in accuracy of one-step-ahead forecasts of GDP growth compared with those obtained by benchmark models. Second, the accuracy of out-of-sample forecasts obtained with models augmented with the RWI is comparable to that of models augmented with established economic indicators, such as the Ifo Business Climate Index and the ZEW Indicator of Economic Sentiment for Germany, and the KOF Economic Barometer and the Purchasing Managers Index in manufacturing for Switzerland. Our results are robust to changes in estimation/forecast samples, the use of rolling versus expanding estimation windows and the inclusion of a web-based recession indicator from Google Trends. As our indices are timely and simple to construct, they could be replicated in countries or regions where no reliable economic indicators exist or their provision is very costly. 相似文献

This study explores the question of whether the Swedish innovation output of the 1970s and 1980s (and the following decades) indicates structural lock-in or renewal. It is motivated by inconsistent explanations in the current literature about the relation between the economic slowdown and subsequent industrial renewal, as well as a lack of research focusing, in this context, on the primary driver of economic growth and structural change: innovation. By observing the number and type of innovations as they hit the market, the data in this paper tell a real time story about micro level innovation activity during the time that the economic crisis unfolds. The analysis considers Swedish innovation output between 1970 and 2007, characterising the number of significant innovations, their novelty, and their origin (including size of firm and industry sector). Three central findings emerge, defined by both the time period and the character of innovations. First, the magnitude of innovation activity peaks in the late 1970s to early 1980s. Second, starting in the late 1970s, small firms begin to outperform large firms in terms of both innovation quantity and quality (i.e. world market novelties). Third, the 1980s saw a distinct shift in the industrial origin of innovations, with software and telecom becoming the leaders in innovation output. The findings suggest that the observed industrial renewal is more nuanced than what has emerged from previous research. 相似文献

This work complements some of the results appearing in the article “Publishing Performance in Economics: Spanish Rankings” by Dolado et al. (Span Econ Rev 5: 80–103, 2003) Specifically we focus on the robustness of the results regardless of the time span considered, the effect of the choice of a particular database on the final results, and the effects on changes in the unit of institutional measure (departments vs. institutions as a whole). Differences are significant when we expand the time period considered. There are also significant but small differences if we combine datasets to derive the rankings. Finally, department rankings offer a more precise picture of the situation of the Spanish academics, although results do not differ substantially from those obtained when overall institutions are considered. 相似文献

In 2003 the World Bank (WB) and the International Monetary Fund (IMF) published estimates of macro-economic indicators for 2002 of the economy of Palestine. The WB used a micro-founded recursive dynamic computable general equilibrium (CGE) model, calibrated on the 1998 Social Accounting Matrix (SAM) of Palestine, to which shocks were applied, whereas the IMF based its estimates on a macro-founded income-expenditure model relying on more recent data. It turned out that there were substantial differences: the estimate by the WB of the real gross national income (at 1998 prices) was 25% less than the corresponding figure calculated by the IMF. This huge difference is not only relevant for a full understanding of the economic consequences of the intifada, but also for the size of the international community intervention. In this paper we propose our own evaluation with the help of a static CGE model, based on the 1998 SAM and the so-called intifada shock derived from data of the WB that we constructed for the analysis of some forms of emergency assistance in a previous article. It turns out that our estimates, based on an entirely different methodology, are remarkably close to those of the IMF. 相似文献

Based on a novel extension of existing multivariate Markov-switching models, we provide the reader with a useful tool for analyzing current business conditions and making predictions about the future state of the Euro-area economy in real time. Apart from the Industrial Production Index, we find that the European Commission Industrial Confidence Indicator, which is issued with no delay, is very useful for constructing the real-time predictions. 相似文献

The relationship between GNP and nutritional status between countries shows a high correlation. This study of two countries with the same GNP (Thailand and Philippines) investigated their use of equal resources and the impact on nutritional status. Malnutrition is more prevalent in the Philippines than Thailand despite an extensive national nutrition programme in the Philippines, better medical and educational services and safer water supplies. The most important underlying economic factor is not income distribution but rather the cost of living, particularly for basic needs. Finally, it is concluded that although GNP is closely related to nutritional status between countries, the longitudinal correlations within a country are much weaker. 相似文献
