Law, guns and money in Brazil

This paper studies the effects of legislation in Brazil that banned the right- to-carry guns and provided for a voter referendum regarding whether to ban the sale of all firearms. Using a regression discontinuity design, I find that gun-related homicides decreased by 12.2 percent, with the reduction especially pronounced in high-crime areas and among black males. There is no evidence of substitution effect as non-gun-related homicides were not affected. Analysis of the subsequent voter referendum, which was defeated by a wide margin, shows stronger support for the complete weapons ban in the areas more affected by gun violence.

Rising UK house prices

The big rise in UK house prices relative to incomes between 1985 and 2018 can be more than accounted for by the substantial decline in real risk-free interest rates over the period. This is slightly offset by net increases in home-ownership costs from higher rates of tax.

These are the findings of a new research report by David Miles of Imperial College London and Victoria Monro of the Bank of England. Their analysis predicts that a 1% sustained increase in index-linked gilt yields from current rates could ultimately result in a fall in real house prices of around 20%.

Exporting pollution

Multinational firms headquartered in countries with strict environmental policies choose to conduct their polluting activities in foreign countries with relatively weaker policies. These effects are stronger for firms in pollution-intensive industries and firms with poor corporate governance. But while firms based in countries with strict policies are more likely to export pollution abroad, they nevertheless produce fewer overall carbon emissions globally.

These are among the findings of a new research report by Itzhak Ben-David (Ohio State University, Stefanie Kleimeier (Maastricht University) and Michael Viehs (University of Oxford). Their results highlight the importance of collective action to combat climate change given the global scale of many firms’ operations.

Fiscal standards for Europe

The European Union should abandon the fiscal rules intended to put constraints on national budgetary policies in favour of fiscal standards – qualitative prescriptions that leave room for judgment together with a process to decide whether the standards are met.

That is the central conclusion of a new research report by Olivier Blanchard (Peterson Institute), Alvaro Leandro (CaixaBank Research) and Jeromin Zettelmeyer (International Monetary Fund). The authors note that their proposals would mark a major departure from the status quo, requiring Treaty change.

Special US Panel meeting on global imbalances and aid

In February, Economic Policy organized a special Panel Meeting, hosted by the Federal Reserve Bank of New York, to discuss the very pressing issue of global imbalances and the fundamental question of foreign aid. The meeting brought together some of the world’s foremost thinkers on these matters, including Jeffrey Frankel, Paul Krugman, Philip Lane and Bill Easterly. A lively debate followed the presentations of each of these preeminent speakers, as participants focussed not only on defining the issues, but on what can be done to alleviate or improve them. Some of these thoughts were captured on film, in a series of short interviews, presented here on the Economic Policy site for the first time. We hope you will enjoy them.

Jeffrey Frankel interviewed by Georges de Menil
on the Renminbi and global imbalances
(13min, 52secs)

What is the role of the Renminbi in the imbalances that have built up between China and the US? The exchange rate is not at the root of the problem, argues Frankel: “the US trade deficit is not China’s fault”, it is instead a result of the exceptionally low US savings rate. But the Renminbi could be part of the answer, which is in the interest of both China and the US. And given the stakes at hand, maybe it should be the role of the IMF to oversee an agreement or at least the drafting of a contingency plan.

Paul Krugman interviewed by Georges de Menil
on financial markets and global imbalances
(15min, 32secs)

Have things really improved since the early days of experimentation with open capital markets and floating exchange rates? Not really, suggests Krugman. Market participants – the real drivers of short to medium run trends – are characterized by bounded rationality, mainly because “it doesn’t pay to think of the sustainability of the US deficit”. “Markets go for long periods where they appear to be defying fundamentals… I think that is what is happening in the case of the dollar right now,” argues Krugman, while still thinking ahead: how likely is a crash of the dollar and what circumstances could mitigate its effects?

Philip Lane interviewed by Richard Portes
on Europe and global imbalances
(15min, 3secs)

“The EU, although it trades a lot with the world, is primarily an internally focussed economy,” argues Lane. Unfortunately, given the EU’s recent history of small, separate states, that is not a common realization among politicians who continue to focus on questions of exchange rates rather than worry about domestic-driven growth and reforms. Even a sudden and large depreciation of the dollar would leave the EU relatively unscathed, as its direct exposure to the dollar is limited in its trade and financial portfolios.

William Easterly interviewed by Georges de Menil
on the effectiveness of foreign aid
(24min, 32secs)

“No-one is ever individually accountable for anything” in the world of foreign aid, argues Easterly. And that is the biggest problem. Haven’t we learned in economics that collective responsibility doesn’t work? That good performance needs to be rewarded and poor performance penalized? And that goals should be measurable and attainable? Yet, these simple lessons are nowhere to be seen in the development world. A rethinking of aid along these lines is necessary and could lead to a multitude of small, incremental yet very tangible and immensely useful improvements. Let’s start with that; economic growth and development “can [anyhow] probably only be done by the poor people themselves.”
