The purpose of the paper is to examine the interdependencies between trade and environment policies, as they get jointly determined in a political‐economy model of a small open economy. In theoretical literature, government is usually modeled as benevolent. In real economies, however, it is not a pure social welfare maximizer. Lobbies have stakes in the specific policies, and they negotiate with/bribe the government over the latter's policy stance. The influence of industry lobbying on both trade and the environment policies at the political equilibrium is the focus of the paper.

Concepts from non‐cooperative game theory are used to incorporate a Nash‐bargaining game between the industry lobby and government. Government is not benevolent. Campaign contributions help win elections and provide incentive to distort policies to attract lobby contributions. Several situations are modeled. Given a politically set environment policy, tariffs may be zero in view of the free trade agreements. Or, a sequential game is modeled where environment policy is set to maximize social welfare, given a politically determined trade policy. Alternatively, in the full political equilibrium, government and lobby bargain simultaneously over tariff and the environmental tax.

Lobbying implies that government may trade‐off one policy for another. When only environment policy is politically manipulable by the lobby, pollution tax is lower than the Pigouvian tax. If, instead, the lobby can influence trade policy only, government provides protection to domestic import‐competing sector. In a sequential game, the trade policy outcome does not change, but pollution tax is always higher than the Pigouvian level, even with the environmental lobby absent. With both the policies political, the government “concedes” and offers positive tariff protection, but, not on environment policy; that is, imposes a pollution tax higher than the Pigouvian level.

The paper provides useful insights into how, under the influence of special‐interest politics, and bargaining between the government and lobbies, the trade and environment policies interact with each other. In comparison with the existing literature on this issue, it derives several stronger and (apparently) counter‐intuitive conclusions.

This paper qualitatively explores arguments in the UK meat tax debate, including how they align with values from specific political ideologies and perspectives on sustainable food security.

The authors conducted a scoping media analysis of articles published over 1 year in six leading UK newspapers, followed by semi-structured interviews with ten key stakeholders in late 2019. The authors identified categories of arguments, distilled the core conflicts and analysed how arguments reflected different ideas about human nature, the role of the state and solutions to food system challenges.

Arguments were categorised into five major topics: climate change and environment; human health; effects on animals; fairness; and acceptability of government intervention. Pro-meat tax arguments often aligned with modern liberal ideology, and sometimes echoed demand restraint or food system transformation perspectives on sustainable food security. Arguments against meat taxes were more likely to align with the efficiency perspective or classical liberal ideology.

To the authors’ knowledge, this is one of the first interpretive analyses of this controversial suggested policy. Despite having similarities with other debates around taxation – particularly taxes on sugar sweetened beverages – the meat tax debate contains unique complexities due to the prominence of environmental arguments, and differing values pertaining to animal welfare and rights. This study highlights the need for policy research exploring values, in addition to quantitative evidence.

Although the federal gasoline tax played multiple roles in financing surface transportation infrastructure in the United States, experts did not agree on the tax's purpose. Some argued that it was essentially a fee for users of the nation's federally supported highways. Others suggested that it should play a more prominent role in environmental, energy, and transportation policy by correcting for driving-related externalities. Still others suggested that it should be used to reduce the federal budget deficit. Finally, the tax itself had remained at the same level since 1993, and with the Highway Trust Fund virtually insolvent, many experts believed it was time for an increase. The case presents a background on the U.S. federal gasoline tax, an overview of the market for gasoline in the United States, and survey of gasoline taxes in U.S. states as well as several other countries around the world.

The case can be used to discuss the incidence of the gasoline tax, as well as its role as a Pigouvian tax to deal with negative externalities related to gasoline consumption and driving. There is sufficient data in the case to enable students to analyze the incidence of the federal gasoline tax and to determine the socially efficient level of the tax in light of externalities related to gasoline consumption and driving.

Social media networks make their services freely available to all users. Users pay for the service received with the time and attention taken by the advertisements. This chapter argues that social media platforms are a unique form of monopoly driven by “the more the merrier” effect (i.e., network effects) in users' consumption. These monopolies exercise market power, not by charging higher prices to users but by “tying” larger amounts of advertising to their content. Traditional antitrust instruments designed to address excessive pricing and reduced output by monopolies need to be reframed to tame the attention economy problems in the social media industry. This chapter discusses five antitrust instruments grouped in three categories: structural, behavioral, and market-based remedies. Market-based solutions are the least explored in the literature, despite being the most promising instruments to lower the attention costs imposed on users, while preserving the economies of scope in production and the network effects in consumption, and possibly maintaining free access to social media, as we know it today.

Introduction – As a financial instrument, tax has always been one of the policy support instruments that governments apply to solve problems. The issue of the environment, on the other hand, is a notion that has gained more importance over the past years and governments struggle to create solutions to environmental problems on the global scale. Climate change is one of the most important parts of this issue. Especially in our modern day, as a result of natural disasters, forest fires and landslides, climate change has become a field in which serious political measures should be taken. Although it has become necessary to implement tax as a tool to decrease carbon emissions and to open new fields for works with less carbon emission, the expected/desired results about carbon emissions have not been obtained throughout the world.

Purpose – The aim of this chapter is to examine carbon taxes, which are the tax applied against climate change, and to draw attention to the multiple policy approach in the face of global environmental problems.

Methodology – This chapter, in which qualitative research method is adopted, has descriptive elements. In this context, an evaluation has been put forward in the light of the data obtained from various reports and scientific articles.

Findings – Though tax is indeed considered as an effective political tool among the precautions to be taken, one-dimensional approach might bring along a deadlock in the solution of this problem. In order to improve this approach and the perception towards the environment across society, it is necessary to include other factors that can play an important role in this process such as non-governmental organisations. Consequently, in order to solve the environmental problems which have occurred as a result of human activities, it is essential to minimise the destruction caused by these human activities (although it is not possible to restore it completely). Therefore, a multi-dimensional policy instead of a one-dimensional policy, an environmentally conscious society and state, and cooperation of policy actors on a global scale are basic elements which can play an important role in the solution of the problem.

Examines the economic factors that influenced chemical based agriculture in Australia and the adverse environmental effects of agrochemicals. Reports how technological change, government policies and institutions affected the environment through chemicals. Discusses the effectiveness of alternative policy measures in mitigating these adverse consequences.

The purpose of this paper is to model the role that stakeholders, and especially social responsible consumers play in the process of finding a win–win solution to control production related negative externalities. In this regard, when information asymmetries are present and consumers become knowledgeable about them, consumers with d-preferences for corporate social responsibility (CSR) type of products becomes the driver of the firm strategy.

To accomplish the goals of this paper, the authors proceed to develop a series of theoretical models wherein the social gains and costs of alternative modes of intervention are illustrated. The authors begin with a standard Pigouvian tax model and construct a stakeholder equivalent tax model and finalize the analysis with consumers acting in a shared social responsible behavior with firms as the optimal solution model.

The authors show that proactive disclosure of information asymmetries regarding negative externalities develops a shared social responsibility between consumers and firms. Market-based solutions to the externality problem are achieved under this setting. This solution is preferred to a Pigouvian tax and to a stakeholder equivalent tax. It is concluded that shared social responsibility is the result of the interaction of consumers with d-preferences and the reaction of a socially responsible “firm” willing, and the authors are able to incorporate these preferences as drivers for its strategy.

The main limitation of this paper is in its theoretical nature and specific applications to one case, that of negative externalities in production processes. The implication of this is that the model herein developed needs to be put to the empirical test.

The overall social implications indicate that active reduction of information asymmetries is welfare improving and preferred to government intervention.

This paper is original as it makes use of economic principles to develop a parsimonious model to demonstrate that proactive actions of a firm in response to consumers and stakeholders demands leads to an overall social welfare improvement when negative externalities deriving from production are incorporated into the decision making process of both consumers and firms. These decisions prove superior to government regulations.

Purpose – This chapter shows that in the presence of tourism, the traditional policy prescription, free trade in goods and the standard Pigouvian tax on pollution, is not optimal for a small open economy.

Methodology/approach – The general-equilibrium analysis is employed to study environmental regulations for a small open economy with tourism.

Findings – Foreign tourists consume mainly local non-traded goods in the tourist-receiving economy. Inbound tourism converts formally non-traded goods into tradables, generating a tourism terms-of-trade effect. Owing to this favourable effect, positive tariffs and stricter pollution taxes can actually improve welfare of domestic residents. The optimal rates of tariffs and pollution taxes are derived and explained for the economy with tourism. These positive rates are confirmed by simulations.

Originality/value of chapter – The presence of tourism can alter the welfare implications of the traditional trade policy.
