The Common Agricultural Policy is a system of farm support that was set up by the EU to assist the agricultural sectors of its member states. The CAP accounts for nearly half of the EU’s budget, at approximately £48bn, and combines direct subsidy payments and price support schemes. Economic welfare is concerned with levels of human well-being, and can be achieved through an efficient allocation of resources, thereby maximising consumer and producer surplus.

The UK is one of many countries that now face a dilemma when it comes to fish stocks and their sustainability. In the UK we now consume over 385,000 tons of fish per year whilst on a global scale only 10% of large fish stocks that existed in the 1950s are still present today; this include both cod and tuna. Stock depletion has become a larger issue because of the increases in fishing technology – especially in long-line fishing which is the main technique used in Japan.
As a result many of the once inaccessible fish reserves have become economically viable to fish as boats are more fuel efficient and require less labour. In a fully functioning market the decline in supply of the product would cause an increase in price and act as a disincentive for consumers to purchase the product meaning that the industry would reach a sustainable equilibrium. In this case however there has been a deep market failure resulting from the tragedy of the commons. The sea, and its fish, is a common resource either on a global scale or on a national scale within a country’s own territorial waters. There are very few established property rights over the sea meaning that rational economic agents have an incentive to plunder the seas resources causing the falling fish stock levels.

‘The tragedy of the commons’, although created by Garrett Hardin, is a famous concept which can be traced back to Adam Smith. It refers to a situation where individuals or private economic agents exploit scarce and rival common environmental resources for their own rational, self-interested aims, leading to over-production and the possible permanent depletion of the resource for all.
The essence of this problem stems from insufficient and poorly protected property rights. In other words, as consumers do not own these common goods, they have little incentive to take care of and maintain it, but rather an incentive to extract as much personal utility or benefit from it as possible at that particular time. Therefore, the provision of property rights over some grazing land may help to prevent it being permanently destroyed – instead allowing utility to be extracted from it at a sustainable rate. However, as the tragedy of the commons is a problem where one’s actions affect the benefits of others in the future, concerns for intergenerational equity usually end up being dominated by concerns for personal benefits.

Recent business history both here in the UK and in international markets is littered with examples of cartel-behaviour by businesses that seem to have come unstuck. Just type price-fixing into Google news and see what comes up! Even on the day I am writing this blog answer, the FT reports that three cargo airlines have agreed to pay fines totalling $214m for their roles in a global conspiracy to fix prices for air freight. Bloomberg reports that a former sales executive at Hitachi Displays Ltd. has been charged with participating in a global conspiracy to fix prices for liquid crystal displays sold to Dell Inc. And in Ireland, a former director of a Dublin car company has been given a 15-month suspended prison sentence and fined €160,000 after pleading guilty to charges of price-fixing.

A scrappage subsidy is a “pay-to-scrap” scheme where a government offers a financial incentive to car buyers if they scrap a car that has reached a specified age and in its place they are offered a payment towards the cost of a new vehicle. Germany and France both offer scrappage subsidies to consumers and there is a growing number of voices from inside the UK business community and motor vehicle industry clamouring for one to be launched in the UK. The Retail Motor Industry Federation and the Society of Motor Manufacturers and Traders (SMMT) are at the head of the queue lobbying for a scrappage scheme to be introduced as soon as possible.

Which indirect taxes give the government to most revenue?

For the UK government value added tax provides the biggest source of revenue. In November 2008, VAT was cut from 17.5% to 15% on a temporary basis in a move by the government designed to stimulate consumer spending – the decision was said to be worth around £12 billion of lost tax revenue for the UK Treasury.
There are many other indirect taxes and our chart below highlights six of them. As you can see the flow of tax revenue from indirect taxes on tobacco provides a very important source of money for the UK government. Together these six indirect taxes add nearly £20 billion annually into the government’s coffers.
In a recession where consumer spending is falling and where there is a chance of a period of persistent price deflation, the UK government will see a fall in revenue from indirect taxes.

Q&A: What is a positive sum game?
A positive sum game refers to the outcome of a decision or a policy or a negotiation involving at least one agent. And in this outcome a positive sum game occurs when no one wins at someone else’s expense - indeed the sum of positives and negatives (wins and losses) is positive.
A good example of this are the mutually beneficial gains from trade in goods and services between nations. If businesses or (more generally) countries can find a terms of trade in which both parties benefit then specialisation and trade can lead to an overall improvement in the economic welfare of both countries.
Many environmental campaigners believe that countries should do more to recognise the benefits of cooperation in designing policies and incentives to mitigate the impact of climate change. Surely there are positive sum games from agreement on strategies to lower C02 emissions for example by promoting innovation and the diffusion of technological change?
At a micro economic level positive sum games might be discussed in the context of negotiations between employees and employers or businesses in an oligopoly recognising their mutual interdependence and agreeing to cooperate in ways such as joint research projects (legal under EU competition law). Joint ventures are good examples of businesses understanding the power of collabborrative ventures.
A good recent example of this is the joint venture agreed by O2 and Vodafone to build and share new network sites together. They will share the masts, antennas, cabinets and power supply, as well as consolidate their existing G and 3G masts.
Q&A: What is the Easterlin Paradox?
The Easterlin Paradox concerns whether we are happier and more contented as our living standards improve. In the mid 1970s Richard Easterlin drew attention to studies that showed that, although successive generations are usually more affluent that their parents or grandparents, people seemed to be no happier with their lives? It is an interesting paradox to study when you are writing about measuring economic welfare and the standard of living.

Could you please explain the meaning of externalities in relation to marginal social cost, marginal social benefit?
Externalities are third party effects arising from production and consumption of goods and services for which no appropriate compensation is paid. Externalities occur outside of the market i.e. they affect people not directly involved in the production and/or consumption of a good or service. They are also known as spill-over effects.
