Enforcement and environmental quality in a decentralized emission trading system

Should the powers of monitoring compliance and allocating tradeable emissions allowances be appointed to a unique supranational regulator or decentralized to several local regulators? To answer this question, we develop a two stage-two country game where environmental regulators set the amount of emission allowances and the level of monitoring effort to achieve full compliance while the regulated firms choose actual emissions and the number of permits to be held. Various, possibly conflicting, spillovers between countries arise in a decentralized setting. We show that decentralization is socially harmful if no asymmetry among institutional settings is introduced and can be suboptimal even when decentralization features lower monitoring costs than a centralized setting. Lower monitoring costs are therefore necessary, but not sufficient, to justify decentralization. Also, our analysis reveals that welfare can be higher under decentralization even if the corresponding environmental quality is worse than under centralization. Indeed, better environmental quality is sufficient but not necessary for higher welfare under decentralization. Finally, we discuss how these results can provide a theoretical rationale for the recent evolution of the EU ETS design.     

FROM EXOGENOUS TO ENDOGENOUS ECONOMIC NETWORKS: INTERNET APPLICATIONS

Abstract.  Economic agents' behaviour is affected by their position in a network, either exogenous or endogenous, in which they interact with a sub-set of neighbours only. The network's links, which may be generated by vertical and/or horizontal relations, or by more complex morphologies, may explain the transition between dynamic equilibria and the instability of economic aggregates. Moreover, networks shape strategic interaction among agents by determining their strategies; the problem of access and interconnection, particularly relevant in the Internet, is perhaps the best example. A two-way feedback between strategies and network structures arises instead when links are endogenous: those features are clearly shown in the mechanism underlying the formation of peering links and R & D networks.     

Macroeconomic Effects of Precautionary Demand for Oil

We evaluate the macroeconomic effects of shocks specific to the oil market, which mainly reflect fluctuations in precautionary demand for oil driven by uncertainty about future supplies. A two‐stage identification procedure is used. First, daily changes in the futures–spot price spread proxy for precautionary demand shocks and the path of oil prices is estimated. This information is then exploited to restrict the oil price response in a vector autoregression. Impulse responses suggest that such shocks reduce output and raise prices. Historical decomposition shows that they contributed significantly to the US recessions in the 1990s and in the early 2000s, but not to the most recent slump.

The country-of-origin lie: impact of foreign branding on customers’ willingness to buy and willingness to pay when the product’s actual origin is disclosed

If you think about the last television commercial for an Italian pasta brand you have seen, are you sure it is really Italian? In many cases, especially in the food sector, neither the company nor the product originate from the advertised country, meaning that the company is pursuing a foreign branding strategy and is trying to benefit from positive stereotypes customers have about the specific foreign country. By collecting both quantitative and qualitative data through a point-of-sale intercept survey, this article assesses the impact of alleged origins on customers’ willingness to buy (WTB) and willingness to pay (WTP) if the actual origin is disclosed. The sample consisted of 200 German customers who were asked to answer questions related to one of two hedonic products they had just bought. It is empirically shown that foreign branding has a positive impact on the brand’s performance. However, as soon as customers find out that they were misled with regard to the origin of the product, both their WTB and their WTP decrease. This study contributes to the knowledge on the role of products’ origins on customers’ WTB and WTP. In contrast to the vast majority of the studies in this field, the communicated origin of the product is based on a foreign branding strategy and not on the product’s actual origin. Consequently, it was possible to manipulate within-subject variables by disclosing the actual origin of the product. The results of our study suggest that foreign branding may be a successful strategy for companies to increase their customers’ WTB and WTP. At the same time, our results raise concerns about the suitability of foreign branding as a long-term marketing strategy, unless a company can successfully maintain its foreign image. Future research opportunities include the choice of consumers with a different cultural background, of other hedonic products or of utilitarian products.     

Risk cultures and dominant approaches towards disasters in seven European countries

This paper builds upon the risk culture concept started with Mary Douglas’ and Aaron Wildavsky’s seminal work on risk and culture. Based upon the empirical results of a qualitative sociological study on sociocultural factors affecting risk perception and crisis communication in seven European countries, a theoretical model, illustrating how differences in disasters framing imply diverse approaches to risk and disaster management, is suggested. According to this framework, culturally bounded assumptions and conventions strongly influence how communities make sense of risks and hazards and how these communities consider some ways of dealing with disasters more appropriate than others. The framework suggested in this article distinguishes between risk cultures of a given society, which do not necessarily respond to nation states. In order to explain differences in how cultures deal with risks and disasters, and to define the main features of our typology, three main interrelated dimensions have been selected: disaster framing, trust in authorities and blaming. By analyzing differences and similarities in how people perceive and interpret disasters, as well as to whom the responsibility for risk prevention and crisis management is attributed, in seven European countries, three specific ideal types of risk cultures emerged: state-oriented risk culture, individual-oriented risk culture and fatalistic risk culture. Implications for crisis management and communication in case of a disaster will be addressed for each of these risk cultures.

Banks' noninterest income and securities holdings in a low interest rate environment: The case of Italy

Using a sample of 440 Italian banks over the period 2007–2016, we find that low interest rates motivate banks to expand their fee and commission income and to restructure their securities portfolios. A granular breakdown suggests that banks grow noninterest income in various ways, including portfolio management, brokerage and consultancy services and increase fee income from current account and payment services. In addition, banks rebalance securities portfolios away from those “held for trading” to securities “available for sale” and “held to maturity.” Our findings allude to different behavior between large and small banks: while larger banks increase brokerage, consultancy and portfolio management services, smaller banks generate fees from customer current accounts.     

Comparing the effectiveness of employment subsidies

This paper examines the implications of different types of employment subsidies for employment, welfare, and inequality. It investigates how these effects depend on what target groups the subsidies address. Our analysis focuses on policies that are “approximately welfare efficient” (AWE), i.e. policies that (a) improve employment and welfare, (b) do not raise earnings inequality and (c) are self-financing. We construct a microfounded, dynamic model of hiring and separations and calibrate it with German data. The calibration shows that hiring vouchers can be AWE, while low-wage subsidies are not AWE. Furthermore, hiring vouchers targeted at the long-term unemployed are more effective than those targeted at low-ability workers.     

What’s up after brain drain? Sometimes, somewhere, someone comes back: a general model of return migration

Individual preferences and wage differentials are generally interpreted as determinants of agents?? migration decisions in search of job opportunities. Literature about migration flows usually describes both theoretical and empirical evidence for either temporary or permanent movements of workers, but brain drain migration has its own peculiar characteristics. This paper aims to obtain two results: the first is to present the law of determination that leads to the moment of the return decision, and the second is to analyse how the difference between the utility from domestic and foreign consumption evolves in time. The presented model explains how the return decision is determined, even in cases when the agent does not leave or does not return at all.     

Unemployment accounts and employment incentives

We explore the far-reaching implications of replacing current unemployment benefit (UB) systems by an unemployment accounts (UAs) system. Under the UAs system, employed people are required to make ongoing contributions to their UAs and the balances in these accounts are available to them during periods of unemployment. The government is able to undertake balanced-budget interpersonal redistributions among the UAs. At the end of their working lives, people could transfer the remaining balances on their UAs into their pensions.We present an analytical framework to analyse the incentive effects of UAs and calibrate our model for the high high-unemployment countries of Europe. Our results suggest that this policy reform would significantly change people's employment incentives and could achieve reductions in unemployment without reducing the level of support to the unemployed.
