Climate and happiness

Climate is an important input to many human activities. Climate affects heating and cooling requirements, health, clothing and nutritional needs as well as recreational activities. As such, it is to be expected that individuals will have a preference for particular types of climate. This paper analyses a panel of 67 countries attempting to explain differences in self-reported levels of happiness by reference to, amongst other things, temperature and precipitation. Various indices are used for each of these variables, including means, extremes and the number of hot, cold, wet and dry months. Using a panel-corrected least squares approach, the paper demonstrates that, even when controlling for a range of other factors, climate variables have a highly significant effect on country-wide self-reported levels of happiness. On the basis of these results, it is determined that differential patterns of anthropogenically induced climate change might alter dramatically the distribution of happiness between nations, with some countries moving towards a preferred climate and others moving further away. We find that high-latitude countries included in our dataset might benefit from temperature changes. Countries already characterized by very high summer temperatures would most likely suffer losses from climate change.     

An analysis of public adaptation to climate change using agricultural water schemes in South America

This paper provides an analysis of public adaptation to climate change using agricultural water schemes in South American farms. Unlike other studies of adaptation, this paper examines the differences between private irrigation and public irrigation schemes based on around 1400 farm surveys collected across seven countries in South America which recorded detailed water schemes. We analyze the choice of water schemes in the first stage and the land values for each scheme in the second stage. We find that public irrigations do not increase in response to a warmer climate, but private irrigations do. On the other hand, we find that public irrigation schemes are provided primarily as a response to water scarcity. Moreover, we find that private irrigations are taken gradually while public irrigations are provided as a lump sum, resulting in either too much or too little provision. Therefore, public adaptations to climate change will likely involve two inefficiencies. No provision of irrigation in a hotter climate may result from a lack of knowledge. Overprovision of irrigation in dry zones may result from a lump-sum provision of a public good.

Dynamics of public opinion and policy response under proportional and plurality elections

We compare the patterns of adjustment of government policy to changes in public opinion in the Netherlands and the United Kingdom. These countries are similar in many ways, except that the United Kingdom has plurality elections and single-party government, while the Netherlands has proportional representation (PR) and coalition government. This provides the first application of the Macro Polity approach to a country with PR elections. We find that government policy in the Netherlands is highly responsive to public opinion. This cannot be the result of alternation of government, but instead must be the result of some other process, such as coalition bargaining. In the United Kingdom, however, the dynamic of adjustment is far more complex. Alternation of government does not produce responsiveness, but rather seems to get in the way of it. This leads to an over-correction dynamic in which policy can be out of line with public opinion for long periods of time.     

MEASUREMENT OF THE ROLE O F THE PUBLIC SECTOR IN THE FINNISH ECONOMY

Following the growth of the public sector traditional measures of the size of the public sector have appeared to be inadequate for policy purposes. In the article the role of the public sector in the Finnish economy is described first by using some traditional methods and indicators. The historical background of the development is briefly discussed. After that some specific problems of the measurement are discussed. These problems include measurement of output and productivity, definition of appropriate balance of the public sector, different measures to describe the size and scope of the public sector, role of tax reliefs and subsidies, different organizational arrangements, public sector regulation etc.
The growth of the public sector takes many different forms and it appears to be more difficult than formerly to obtain a comprehensive picture of the scope of the public sector. For different purposes different indicators have to be used. At the end of the paper the implications of the changing emphasis in the public policy are discussed.     

UNION ORGANIZING AND THE REAGAN NLRB

President Reagan's appointees to the National Labor Relations Board (NLRB) have issued many controversial decisions. This has caused a debate between liberals viewing the Reagan NLRB as anti-union and conservatives viewing the recent NLRB decisions as a return to proven and appropriate policies. This paper investigates Reagan NLRB decisions over the years 1982-1986 so as to shed some light on the facts underlying the debate. The analysis reveals that the Reagan NLRB decisions have been either favorable to employers or unfavorable to unions. The NLRB's decisions undoubtedly contribute to the organizing difficulties faced by unions.     

Nested externalities and polycentric institutions: must we wait for global solutions to climate change before taking actions at other scales?

The literature on global climate change has largely ignored the small but positive steps that many public and private actors are taking to reduce greenhouse gas emissions. A global policy is frequently posited as the only strategy needed. It is important to balance the major attention on global solutions as the only strategy for coping with climate change. Positive actions are underway at multiple, smaller scales to start the process of climate change mitigation. Researchers need to understand the strength of polycentric systems where enterprises at multiple levels may complement each other. Building a global regime is a necessity, but encouraging the emergence of a polycentric system starts the process of reducing greenhouse gas emissions and acts as a spur to international regimes to do their part.     

A THEORY OF THE INFORMAL SECTOR

In many countries, especially poor countries, a heavy burden of taxes, fees, bureaucratic hassles, and bribes drives many producers into an informal sector. This paper shows that we can attribute the existence of a large informal sector to the fact that, because productive endowments contain important unobservable components, the state cannot adjust the amounts that it extracts from producers in the formal sector finely according to each producer's endowment. Given this fact, we find that if the endowment of well-endowed producers is sufficiently large relative to poorly endowed producers, or if their number is relatively large, or if the quality of public services is sufficiently low, then the state extracts a large enough amount from producers in the formal sector that poorly endowed producers choose to work in the informal sector. This result obtains both for a proprietary state, which maximizes its own net revenue, and for a hypothetical benevolent state, which would maximize total net output. But, we also find that there exist combinations of the distribution of endowments and the quality of public services such that the policies of a proprietary state, but not the policies of a hypothetical benevolent state, would cause poorly endowed producers to work in the informal sector.     

Is public capital productive in Europe?

This paper addresses the issue of whether and by how much public investment or public capital can increase GDP. In comparison with the literature on the subject, we apply many different methodologies to answer these questions. A vector autoregressive (VAR) model (for France, Italy, Germany, the UK and the USA), a panel composed of 6 European countries (Austria, Belgium, France, Germany, Italy and the Netherlands) and a regional panel (French regions) are estimated. Public investment is shown to be a significant determinant of output; this is also true for public capital but to a lesser extent than public investment with a VAR methodology. The size of the estimated coefficient is also more realistic than those obtained in the literature. This empirical result confirms that the focus of some economists on safeguarding the level of public investment is not misplaced. The debate on the introduction of a ‘golden rule of public finance’ in the European Monetary Union is legitimate in this respect.     

SIZE OF THE PUBLIC SECTOR,ECONOMIC GROWTH AND THE INFORMAL ECONOMY: DEVELOPMENT TRENDS IN THE FEDERAL REPUBLIC OF GERMANY*

The growth of the public sector in the post-war period and the consequences of this development for economic growth is a strongly disputed subject of economic theory and policy. In this paper the development trends of state activities in the case of the Federal Republic of Germany are presented. The structure of public expenditures as well as the tax structure are taken into consideration and possible impacts on real economic growth are analysed. The negative correlations between some kinds of public expenditures (or taxes) and the growth rate of real GNP should not be taken in proof of the growth-retarding effects which might ensue from increasing state activities. It seems to be more likely that state activities have induced shifts of resources from the formal into the informal economy. Politicians should be aware that some measures of economic policy conventionally proposed will strengthen the movement into the informal economy, thus intensifying the current problems within the public budgets as well as in the social security system.     

Comparative assessment and essential analysis on new international GHG emission reduction proposals

Since Kyoto Protocol came into force on February 16, 2005, the endeavor by international society to combat the climate change has stepped into a new milestone. The greenhouse gas （GHG） abatement mechanisms in Kyoto Protocol have served a remarkable function but also been questioned during the practices of past three years about its environmental effectiveness. A lot of new international GHG emission reduction proposals are proposed from many new a.spects, some of which especially impose pressure on developing countries. So it is of great importance to research on these new proposals in time for negotiation beyond Kyoto and institution of Chinese relevant climate policies. As this paper focutses on the way of commitment distribution of mechanisms, the mechanisms here are categorized in one of two types： those distribute commitment based on countries and those based on sectors. Some of the typical mechanisms are selected to be analyzed comparatively, especially about their influence on developing countries,E-mail address： jiangdongmei@tsinghua.edu.cn     

THE GOVERNANCE CHALLENGES OF SOCIAL ENTERPRISES: EVIDENCE FROM A UK EMPIRICAL STUDY

ABSTRACT:  The social enterprise sector in the UK is going through a period of rapid growth, and is being seen by government as another important vehicle for delivering public services. As a result the issue of public trust in social enterprise is of growing importance. While there is a growing literature on the governance of voluntary and non-profit organizations, with some exceptions (e.g. co-operatives) there has been little research on the governance challenges and support needs of social enterprises. The research reported here aimed to help fill that gap. Based on interviews and focus groups with governance advisers, board members and chief executives it explores the typical governance challenges faced by social enterprises. Based on the research the paper develops a new, empirically-grounded typology of social enterprises based on their origins and development path, and presents findings about some of the governance challenges that are common across the sector and some that are more distinctive to the different types of social enterprise.     

Profiting in the info-coms industry in the age of broadband: Lessons and new considerations

Who profits in the info-coms industry in the broadband age, and how? This paper looks at this question by considering broadband as quite a broad phenomenon, including both the most important focus in the current evolution of the Internet, high speed access, and the new services created. We focus on two key stylized facts: SF1: “R&D and patent licensing are increasingly high in this industry, but the initiators of innovations have greatly changed over time”, and SF2: “Small, facilities-less companies contributed to the development of the Internet industry, but have generally performed badly as the industry has matured and broadband use has become widespread”. The paper uses the approach developed by Teece (1986) which analyses strategies of integration, collaboration, licensing and public policy in the presence of technological innovation. These organizational strategies, in practice, are not all profitable and, as Teece correctly stressed as a general principle, their success appears to depend to a great extent on whether they are initiated by innovators or imitators, and how they are articulated within a) regimes of appropriability, b) dominant design issues, and c) complementary assets access. The paper analyses the robustness of Teece (1986), which over the last twenty years has greatly influenced research in economic organization and business strategy on the issue of profiting from innovation, in its ability to provide a framework appropriate to the changes that have occurred in the broadband industry. The paper draws some lessons, and provides some new considerations related to the robustness of Teece's framework. The framework appears robust on SF1: innovators globally have won, though some of them (the best innovators) were acquired by imitators. On SF2, again the innovators have won, but the only success strategy (vertical integration) was only attainable for the largest ISPs/IAPs. We conclude, therefore, that there are many lessons that can be drawn from Teece's framework, though further work should be done on two essential topics: deeper analysis of the sources of technology provision, and investigation of the role of firm heterogeneity.     

Global Warming and a Potential Tipping Point in the Atlantic Thermohaline Circulation: The Role of Risk Aversion

The risk of catastrophes is one of the greatest threats of climate change. Yet, conventional assumptions shared by many integrated assessment models such as DICE lead to the counterintuitive result that higher concern about climate change risks does not lead to stronger near-term abatement efforts. This paper examines whether this result still holds in a refined DICE model that employs the Epstein–Zin utility specification and that is fully coupled with a dynamic tipping point model describing the evolution of the Atlantic thermohaline circulation (THC). Risk is captured by the possibility of a future collapse of the circulation and it is nourished by fat-tailed uncertainty about climate sensitivity. This uncertainty is assumed to resolve in the middle of the second half of this century and the near-term abatement efforts, which are undertaken before that point of time, can be adjusted afterwards. These modelling choices allow posing the question of whether aversion to this specific tipping point risk has a significant effect on near-term policy efforts. The simulations, however, provide evidence that it has little effect. For the more likely climate sensitivity values, a collapse of the circulation would occur in the more distant future. In this case, acting after learning can prevent the catastrophe, implying the remarkable insensitivity of the near-term policy to risk aversion. For the rather unlikely and high climate sensitivity values, the expected damage costs are not great enough to justify taking very costly measures to safeguard the THC. Our simulations also provide some indication that risk aversion might have some effect on near-term policy, if inertia limiting the speed of decarbonisation is accounted for. As it is highly uncertain how restrictive this kind of inertia will be, future research might investigate the effects of risk aversion if additional uncertainty about inertia is considered.     

THE EFFECTS OF 1996 FARM LEGISLATION ON FEED AND FOOD GRAINS

The 1996 Federal Agricultural Improvement and Reform (FAIR) Act of 1996 has been portrayed as a radical departure from the farm policies of the past 60 years. FAIR brought sweeping institutional changes to the basic price and income support programs, many of which had been in place since the 1930s. Close analysis reveals that many of the reforms of the FAIR Act are less revolutionary innovations and more continuations of reforms that began with the 1985 farm legislation and were extended by the 1990 farm bill. Nor should one believe that the changes will result, as some suggest, in large changes in crop acreages or have large effects on the year-to-year variability offarm revenues for these crops. In both cases, the changes in policies may be substantive, but their effective consequences are modest.     

气候变化视野中的自愿环境协议

气候变化问题的综合性和广泛性决定整个社会每一分子都直接或间接地对气候变化有不可分割的作用。传统环境治理思想过多地将环境管理和提高义务置于诸如政府、环保团体等公共利益卫道士之手,单纯依靠公共利益团体的力量在气候变化背景下已不足以形成有效的社会约束机制,许多高瞻远瞩的企业已意识到自身环境责任与社会形象的重要性,通过自我约束行为为缓解气候变化添砖加瓦,自愿环境协议为此提供了制度平台。国际上早已有将自愿环境协议作为气候变化应对战略的一项重要措施的实践,我国的相关试点工作也已悄然铺开。因此,如何正视自愿环境协议的柔性治理功能,以及如何促进其在我国气候变化应对机制中发挥正面作用,成为我国环境治理面临的新问题。     

Elements of the institutionalization process of the forest and pasture commons in Romania as particular forms of social economy

In Romania, the study of jointly owned property (dev?lm??ie) has been of great interest for social scientists during the different political regimes of the country. After the fall of the communist regime and after over 50 years of state ownership, the forests and pasture commons (ob?ti and composeorate) returned to be private property of newly established associative forms. This paper aims to identify and define the contemporary Romanian commons by reference to the general characteristics of social economy organizations. In order to achieve this and obtain a clearer view of the place of the commons in Romania's organizational environment, presentation of some elements of the commons’ institutionalization process after the fall of the communist regime is included. The data used for answering these two objectives comes from the analysis of a database comprising 328 questionnaires applied to board members of commons in Romania and various legal documents. The main argument of the paper is that the restitution process that led to the re‐establishment of the Romanian commons from public property to common private property—marked by hardships, conflicts, misunderstandings or faults—deepened the scarce knowledge of the political actors, general public and other stakeholders in regard to these organizations and perpetuated their unclear position in the organizational field.     

THE INTERNATIONALIZATION OF AGRICULTURAL TECHNOLOGY: PATENTS, R&D SPILLOVERS, AND THEIR EFFECTS ON PRODUCTIVITY IN THE EUROPEAN UNION AND UNITED STATES

Multilateral indices of total factor productivity (TFP) allow efficiency comparisons between ten European Union countries and the United States from 1973 to 1993. Differences in TFP levels are then explained by land quality differences, public research and development (R&D) expenditures, education levels, private-sector patents, international spillovers of public R&D, and private-sector technology transfer. There is evidence that public R&D results in limited knowledge spillovers between the European countries and the United States. However, the use of international patent data from the Yale Technology Concordance shows not only that patents matter, but also that private sector technology transfer may be the dominant force in explaining TFP trends. The United States and the European Union countries with more advanced research systems (Netherlands, Denmark, France, and Belgium) converge in a high-growth club, while Germany, Luxembourg, Greece, Italy, Ireland, and the United Kingdom form the slow-growth group. Ignoring knowledge spillovers and technology transfer leads to biased estimates of R&D elasticities, which is hardly surprising since the private sector is now spending more than the public in some of these countries. Thus, the estimated rate of return to public agricultural R&D falls from over 60% in the closed economy model to 10% in the model that takes account of international spillovers. (JEL Q16)     

A Ricardian Analysis of the Distribution of Climate Change Impacts on Agriculture across Agro-Ecological Zones in Africa

This paper examines the distribution of climate change impacts across the sixteen Agro-Ecological Zones (AEZs) of Africa. We combine net revenue from livestock and crops and regress total net revenue on a set of climate, soil, and socio-economic variables with and without country fixed effects. Although African crop net revenue is very sensitive to climate change, combined livestock and crop net revenue is more climate resilient. With the hot and dry CCC climate scenario, average damage estimates reach 27% by 2100, but with the mild and wet PCM scenario, African farmers will benefit. The analysis of AEZs implies that the effects of climate change will be quite different across Africa. For example, currently productive areas such as dry/moist savannah are more vulnerable to climate change while currently less productive agricultural zones such as humid forest or sub-humid AEZs become more productive in the future.
