The transition to net zero involves deep structural transformation of the global economy and its associated complex socio-technical systems. Here, we set out a conceptual framework to identify ‘sensitive intervention points’ (SIPs) in systems where a small or moderately-sized intervention could drive outsized impacts and transformational change. These points take three forms: (i) critical tipping points, such as a critical price threshold, (ii) critical nodes in networks, such as an influential actor in a social network, and (iii) critical points in time, where windows of opportunity for change open up. We also propose an assessment methodology for prioritizing interventions in terms of their potential impacts, risks, and ease of implementation. We apply our framework and assessment methodology to evaluate a list of proposed interventions for accelerating global decarbonization. Promising interventions include investing in key clean energy technologies with consistent cost declines, introducing central bank policies to reduce the value of polluting collateral, and enhancing climate-related financial risk disclosure.","PeriodicalId":48024,"journal":{"name":"Oxford Review of Economic Policy","volume":"529 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138528769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By providing new evidence on cantonal top wealth shares for each of the 26 cantons since 1969, we show that the overall trend masks striking differences across cantons, both in levels and trends. Combining this with variation in cantonal wealth taxes, we then estimate an event study model to identify the dynamic effects of reforms to top wealth tax rates on the subsequent evolution of wealth concentration. Our results imply that a reduction in the top marginal wealth tax rate by 0.1 percentage points increases the top 1 per cent (0.1 per cent) wealth share by 0.9 (1.2) percentage points 5 years after the reform. This suggests that wealth tax cuts over the last 50 years explain roughly 18 per cent (25 per cent) of the increase in wealth concentration among the top 1 per cent (0.1 per cent).","PeriodicalId":48024,"journal":{"name":"Oxford Review of Economic Policy","volume":"291 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136020545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main rationale for a wealth tax is to address the incompleteness of the tax code in taxing unrealized capital gains, which can be enormous and concentrated among the wealthy. However, by taxing presumed rather than actual returns, a wealth tax fails to address inequality among taxpayers with the same wealth but different capital incomes. In addition, wealth taxation creates liquidity problems that may adversely affect growth firms and start-ups, which is why wealth taxes typically provide exemptions and deductions for certain business assets. Our empirical analysis, based on Swedish register data, describes the wealth composition of the wealthiest and assesses the distributional incidence of different combinations of wealth and capital income taxation.","PeriodicalId":48024,"journal":{"name":"Oxford Review of Economic Policy","volume":" ","pages":""},"PeriodicalIF":6.8,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45418835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We emphasize three main rationales for capital taxation. First, the frontier between capital and labour income flows is often fuzzy, thereby lending support to a broad-based, comprehensive income tax. Next, the very notions of income and consumption flows are difficult to define and measure for top wealth holders where capital gains due to asset price effects dwarf ordinary income and consumption flows. Therefore the proper way to tax billionaires is a progressive wealth tax. Finally, as individuals cannot choose their parents, there are strong meritocratic reasons why we should tax inherited wealth more than earned income or self-made wealth for which individuals can be held responsible, at least in part. This implies that the ideal fiscal system should also include a progressive inheritance tax, in addition to progressive income and wealth taxes. We then confront our prescriptions with historical experience. Although there are significant differences, we argue that observed fiscal systems in modern democracies bear important similarities with this ideal triptych.","PeriodicalId":48024,"journal":{"name":"Oxford Review of Economic Policy","volume":" ","pages":""},"PeriodicalIF":6.8,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43285556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We revisit the key aspects of how capital gains are taxed and address the main arguments against taxing capital gains more heavily: (i) it would discourage socially beneficial activities, such as innovation, (ii) implementing structural changes is unadministrable, and (iii) the ‘lock-in’ effect means that increasing the tax rate is an inefficient way to raise revenue. To address concerns with the unpopularity of taxing unrealized gains during one’s lifetime and retroactive taxes, we conclude with a partial proposal for constructive realization at death that would apply only to gains accrued after a certain date, while allowing for discounted pre-payments of tax liability.","PeriodicalId":48024,"journal":{"name":"Oxford Review of Economic Policy","volume":" ","pages":""},"PeriodicalIF":6.8,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47566728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ownership is highly concentrated at the top, but many crypto investors have only moderate incomes.
