The changing legislative landscape of the U.S. wine market provides a scenario to examine the effect of regulation on the size distribution of firms. Using the variation across states and time in the sum of in-state and out-of-state adult populations between 2002–2017, and a difference in difference-style empirical model, I examine how restrictions on Direct to Consumer (DTC) sales impact the number of establishments and the employment at wineries. I find that the expansion of the potential wine market by 10 M adults caused about a 3.5% increase in the number of wineries. While reduced DTC restrictions explain growth in the number of wineries, I find no effect of lessened restrictions on the number of winery employees, though there is evidence of a lagged effect. Additionally, I find that the growth of smaller wineries substantially outpaces that of larger wineries when regulations are lessened. These results suggest that regulatory barriers in particular industries may allow states to maintain an artificial size distribution.

The part of the UK fiscal framework which determines how UK government funding is allocated across the four home nations has undergone profound change since 2012, given tax and social security devolution. The UK government’s post-Brexit plans for regional development funding, state aid, regulation and trade negotiations have led to significant disagreements about the nature of the devolved fiscal and constitutional settlement. And the COVID-19 pandemic provided a major shock to a fiscal system with limited flexibility for the Scottish, Welsh and Northern Irish devolved governments. This paper reviews the changes and challenges faced during these reforms and policy shocks. We find that: tensions about reforms to funding arrangements reflect the inconsistency of principles guiding the reforms; that the UK government’s post-Brexit plans do reduce the policy autonomy of the devolved governments, but reflect powers central governments often have in even highly decentralised countries; and that temporary changes to rules and the nature of the COVID-19 pandemic prevented a subnational fiscal crisis, but that more systematic change may make the system more robust to future shocks. This suggests that a review of the principles underpinning the UK’s subnational fiscal and economic policies would be highly worthwhile.

We study entry policies as an alternative form of environmental policy. Given the strong political opposition to standard output subsidies and taxes, several countries have recently used entry policies to promote renewable energy technology, such as solar panels and biofuels. We study a two-stage game in which two regulators choose an entry policy (i.e., tax, subsidy or permit) to maximize domestic welfare. Observing the policy, firms decide the region in which to enter and compete as Cournot oligopolists. We find that both domestic (uncoordinated) policies and internationally coordinated policies increase welfare relative to unregulated settings. However, the welfare gains from international policy coordination are only large when the product is extremely clean. These results indicate that the welfare gains of international policy coordination may only offset the costs of negotiation in relatively clean industries.

Economic issues will be key determinants of the outcome of the Scottish referendum on independence. Pensions are a key element of the economic case for or against independence. The costs of funding pensions in an independent Scotland would be influenced by mortality risks, the costs of borrowing and the segmentation of costs and risks (i.e. pricing to Scotland's experience rather than pooled across UK experience). We compare the overall costs of providing pensions in an independent Scotland against the resources that are available to cover these costs. Scotland has worse mortality experience than the UK as a whole, and Scottish government debt is likely to attract a liquidity premium relative to UK government debt. An independent Scottish government would have to create a bond market for public debt. The liquidity premium would make pensions cheaper to buy, but taxpayers or the consumers of public services would have to pay the cost.

L'objectif de cet article est de tester économétriquement l'existence d'interactions spatiales entre les choix d'imposition des départements français de métropole. Pour cela, un modèle de choix fiscal avec autorégression spatiale est spécifié pour estimer la pente de la fonction de meilleure réponse qui relie le taux d'impôt d'un département aux taux votés par les départements voisins pour le même impôt. Nous montrons que pour l'année 1999, l'hypothèse d'interactions fiscales horizontales ne peut être rejetée pour trois des quatre impôts départementaux étudiés, notamment pour la taxe professionnelle qui pèse uniquement sur les entreprises. À l'inverse, la fixation du taux départemental de la taxe d'habitation, qui pèse uniquement sur les ménages, ne semble pas gouvernée par les décisions des départements concurrents. Ces résultats sont compatibles à la fois avec les modèles de concurrence fiscale à la Wildasin (1988) et ceux de concurrence par comparaison à la Besley et Case (1995a).
