The Adaptive Investment Effect: Evidence from Chinese Provinces

Posted on by Rhys Williams

A paper of mine, “The Adaptive Investment Effect: Evidence from Chinese Provinces“, co-authored with Dr Kamiar Mohaddes, has recently been published in Economic Letters.

In the paper, we outline that the Adaptive Investment Effect (AIE) is the diversion of investment resources from productive to adaptive capital in response to the effects of climate change. We would expect this diversion to reduce the productivity of investment on economic growth.

For instance, we can imagine that climate change might increase temperatures in some areas. It is well known that higher temperatures reduce labour productivity and so to ameliorate this loss in productivity, firms might invest in air-conditioning units in offices. [...]

Economic Growth: Where does it come from?

One of the fundamental questions of economics is why are some countries rich and others poor? Why do some countries experience heavy growth which allows them to catch-up with the economic giants of the world, whilst others are relegated to the bottom and are unable to jump on the growth train? Is it due to luck, geography, culture or institutional factors? This article explains some of the different theories of economic growth, beginning with the Solow growth model (neoclassical model), before criticising such a model and suggesting that endogenous growth models have more to tell us about the growth phenomenon. We highlights the pitfalls of each model, but conclude that the main reason that incomes are different between countries is due to institutional differences. [...]

International Trade and Economic Growth

Does international trade increase economic growth? In this context, what are the trade policies that have been followed by developing countries?

Standard textbook economic theory tells us that international trade benefits both parties in the trade, based on the gains from comparative advantage as laid out by David Ricardo. However, recent research into New Trade Theory suggests that trade may not always be beneficial, and there are examples when it could inhibit growth. This essay will examine when this could be the case and then relate this to the example of developing countries.

The Ricardian story goes that countries have comparative advantages in producing certain goods. [...]
