ABSTRACT

Information accuracy and decision-making speed are of paramount importance in managing today’s mobility of goods and people inside the city. Intelligent Transport Systems (ITS) can provide road users with updated information and forecasts on both traffic and weather conditions. The result is a higher efficiency in the use of resources and a better management of physical flows. The purpose of this paper is to conduct an in-depth review on the role of ITS supporting urban Smart Mobility, in order to identify the main gaps in the literature and propose future research streams. In total, 71 papers have been thoroughly analysed: they are mainly focused on technology, with limited attention to value creation. Even though some benefits have been examined, a general lack of quantitative models emerged. Eventually, there is a lack of contributions considering both people and freight transport, even if they are strongly related, especially in an urban environment.  相似文献

We study self‐selection into politics and effort once in office of citizens with different abilities and motivations in a framework where moonlighting is allowed. We find that high‐ability motivated (public‐fit) politicians exert higher effort in politics than high‐ability non‐motivated (market‐fit) politicians, and that high‐ability citizens, both public‐fit and market‐fit, may decide to enter politics. We test our predictions using a database of Italian parliamentarians for the period 1996–2006. We find evidence of advantageous selection of both market‐fit and public‐fit parliamentarians. We also show that public‐fit parliamentarians have higher voting attendance and that only voting attendance of market‐fit parliamentarians is negatively affected by income opportunities.  相似文献

This paper examines the presence of a pro-poor bias in the existing structure of protection of six Sub-Saharan African (SSA) countries, Burkina Faso, Cameroon, Côte d'Ivoire, Ethiopia, Gambia, and Madagascar. We build on a simple agricultural household production model and we propose an extension to include adjustments in labor income. Our approach, which can be implemented without repeated cross-sections of household level data, suits well the data constraints in SSA. It also allows us to capture the heterogeneity in trade protection at the tariff line level. The pro-poor bias indicators suggest that SSA's trade policies tend to be biased in favor of poor households, as these policies redistribute income from rich to poor households. This is because protection increases the agricultural prices of goods that are sold by African households and this effect dominates both the impacts of higher consumption prices and the strong Stolper–Samuelson effects that benefit skilled over unskilled workers.  相似文献

Since the start of EMU (Economic and Monetary Union), the euro area, and more broadly the global economy, experienced an unprecedented credit boom. The expansion of credit was particularly strong in Greece, Ireland, Portugal and Cyprus and all of them subsequently needed official financial support. In each of the four programmes, financial assistance has been provided and promised against the commitment of each country to fulfil certain economic policy conditions contained in the macroeconomic adjustment programme. In general, a macroeconomic adjustment is a process driven by policies but also by changes in private spending behaviour (consumption, imports, investment) and improvement in competitiveness that countries are required to undertake after a large shock. In the case of the four countries, the shock emerged as a consequence of an excessive accumulation of imbalances in different parts of the economy: in the public sector in Greece, in the housing and banking sectors in Ireland, external imbalances in Portugal and in the banking sector in Cyprus. The paper looks at the feasibility of the fiscal adjustment comparing the macroeconomic conditions in the four countries and emphasising the role of the fiscal multipliers in the process. It also assesses the fall in the output in a comparative framework, stressing the role played by the different components of demand either in amplifying the effect of the fiscal consolidation or in offsetting it. In addition, it considers formulation of the programmes as well as their implementation with most attention devoted to reforms aiming at improving competitiveness, growth and employment in the framework of a cross-country approach.  相似文献

After the outbreak of the global financial crisis, some governments in the EU experienced serious fiscal problems, while others were less affected. This paper seeks to shed light on the divergent fiscal performance in the EU countries before and after the outbreak of the crisis. Fiscal reaction functions of the primary balance are estimated for different groups of EU countries using quarterly data for the pre-crisis period 2001–2008 and for the crisis period 2009–2014. The pre-crisis estimations reveal some differences in persistence and cyclical reaction between different groups of countries, but in most cases little feedback from the debt stock to the primary balance. The fiscal reaction functions of the countries that eventually developed fiscal problems do not stand out. The estimations on data from the crisis period show largely unchanged persistence and counter-cyclicality but much more feedback from the debt stock, and this applies both to the crisis countries and those less affected. In spite of large deficits and accumulation of debt, the underlying fiscal reaction has become more prudent after the outbreak of the European debt crisis.  相似文献

Few firms grow rapidly, but their contribution to employment growth is often impressive. The main purpose of this paper is to analyse both the external and internal factors that can affect the probability of being a high-growth firm (HGF) in Italy. We found that HGFs are, on average, young firms and are present in different industries, but the role of demand is important to understanding their performance at the sectoral level. Moreover, our findings show that financial constraints and profitability are not associated with the probability of being a HGF. HGFs, on average, are characterised by high productivity, but only when growth is measured in terms of sales. The most original results of this study concern the endogenous determinants of rapid growth, which have yet to be adequately examined in the literature. First, we found that the concentration of ownership is important for HGFs that experienced rapid growth in their sales. Second, the quality of human capital is a strong point for firms experiencing rapid employment growth.  相似文献

In this paper, we use data on 2459 public claims made by 444 politicians from the leading US fact-checking site (PolitiFact) to provide an empirical analysis of false claims in politics, shedding light on their characteristics within an advanced democracy. The frequency of falsehoods differs according to party affiliation and topic, with false claims more likely on such topics as elections, health, labor, taxes and values. For Republican politicians, falsehood pays off in the short run, as it is associated with greater political support.  相似文献

This article contributes to our understanding of cross-border activity in general and the determinants of cross-border trade in particular by focusing on the part of cross-border sales that arise due to work-related cross-border crossings of households. We analyse empirically how cross-border consumption expenditures vary across product and services categories as well as household characteristics using representative household survey data of cross-border commuters to Luxembourg. In total, these households spend an estimated 17% of their gross annual income across the border, contributing about 10% to the total household final consumption expenditure (HFCE) in Luxembourg. Cross-border expenditure is linked to individual- and household-related characteristics and to distance between home and work. Cross-border commuters systematically exploit arbitrage opportunities that arise because of existing price level (index) differences between the country of work and the country of residence.  相似文献
