The Global Economic Balance of Power is Shifting
Will the emerging and developing countries replace the advanced economies?

In recent years, GDP has grown at much higher rates in emerging markets such as China and India than in Western industrialised countries.

7 Risks for the Global Economy
Why we should not rely on sustained economic growth

After the global economy experienced a small dip in growth in 2016, the world's real gross domestic product (GDP) has been growing slightly more strongly since 2017.

Globalization Report 2018: What about the NAFTA Countries?
Interconnectedness of the three countries beyond the FIFA World Cup 2026

The FIFA World Cup 2026 will take place in the three member states of the North-American Free Trade Area (NAFTA) – Mexico, Canada and the United States. This was officially announced today (June 13th, 2018). This huge event will certainly enhance the international interconnectedness of the three countries not only in the fields of sports, but also in many other areas. We take this as an occasion to look at the level of globalization the three NAFTA members have reached already and how much they have benefitted so far from increasing international interconnectedness. We base this analysis on our “Globalization Report 2018“ which we published last week (June 8th, 2018). More ...

For the 3rd time in a row – industrialized countries are biggest winners in globalization

GED Explains: Import Tariffs vs. Import Quotas
Why Import Quotas have the Same Effects as Tariffs on Imports

The US government has postponed the introduction of punitive tariffs on European products such as steel and aluminium for the time being. But instead, they are now considering restricting the volume of exports from Europe through an import quota. In general, such import quotas have the same effects as tariffs on imports, leading to higher […] More ...

Consequences of Punitive Tariffs
What Does History Tell Us?

The historical examples show: politicians and bureaucrats initially find trade barriers to be a suitable means of protecting the domestic economy or certain sectors from foreign competition. However, the economy as a whole suffers over the long term. This also applies to the protected sectors: The necessary adjustments are not made there so international competitiveness continually declines. Compounding the problem, countermeasures adopted by the affected trading partners, cause additional damage to the domestic economy. More ...

What are the challenges for developed industrialized nations?

As part of the economic development process, service sectors in industrialized nations such as Germany have long since established themselves as the most important economic sectors. However, productivity increases in the service sector have been weaker than those in the manufacturing sector. This raises income inequality. Increasing international trade in services could serve to intensify this trend further. More ...

The Global Impact of a Protectionist US Trade Policy
What can theory tell us about how Trump's trade policy might affect the world economy?

Since the election of Donald Trump, there has been a growing danger that U.S. trade policy increasingly relies on protectionist measures. The aim of this policy is to secure jobs and income in its own country. In reality, however, protectionist measures mean that the weakening of international trade triggered by the U.S. is leading to a loss of income worldwide, especially in the U.S. More ...

Nobody Wins with BREXIT
Dynamic Welfare Effects of Brexit Negative for all 28 EU Countries

Since the threat of a Grexit has been averted for the time being, a possible exit of the United Kingdom (UK) from the European Union (EU) poses the next danger for European integration. In our study “Costs and benefits of a United Kingdom exit from the European Union” from April 2015, we analyzed the static effects of a Brexit. We were able to show that due to less cross-border trade activities all 28 EU countries would suffer from lower economic growth. Now we calculated the dynamic growth effects of a Brexit. Again, all 28 economies would be faced with lower growth rates. Growth losses would be even larger than in the case of static effects only More ...
