Социални мрежи за споделяне на риска (Risk -Sharing Social Networks)

Abstract

In this article we survey basic research problems in the economic literature on social networks for risk sharing. Summaryzed are the economic, as well as the social and demographic factors for the formation of risk sharing social networks. Because of the transaction costs for sustaining relationships (information, eforcement cost, etc.) real-life equilibrium networks generally have less then the optimal number of members from a risk sharing perspective. Research results suggest that in the field formal and informal mechanisms for risk sharing function not only as substitutes, but also as complementaries. Enhancing economic distribution can improve risk sharing through an increased penetration of formal shemes in rural areas.

The sociological literature on social networks emphasizes by and large positive network effects. Negative effects of such networks are discussed rather rarely. This paper tackles negative effects by applying economic theory, particularly neoclassical theory, new institutional theory and the results from experimental economics to the concept of social networks. In the paper it is assumed that social networks are exclusive and since exclusiveness affects the allocation of resources, negative external effects may occur. The argument of the paper is that it is not only advantages for network members that need to be investigated but also the disadvantages for non-network members. The results have two implications. The first one is for economic policy, which often fosters social networking while ignoring their negative externalities. The second one is for network research that can benefit from a more rigorous application of economic theories.

Evidence suggests that in developing countries, agents rely on mutual insurance agreements to deal with income or expenditure shocks. This paper analyzes which risk-sharing networks can be sustained in the long run when individuals are far- sighted, in the sense that they are able to forecast how other agents would react to their choice of insurance partners. In particular, we study whether the farsightedness of the agents leads to a reduction of the tension between stability and efficiency that arises when individuals are myopic. We find that for extreme values of the cost of establishing a mutual insurance agreement, myopic and farsighted agents form the same risk-sharing networks. For intermediate costs, farsighted agents form efficient networks while myopic agents don't.

This paper introduces a new model of exchange: networks, rather than markets, of buyers and sellers. It begins with the empirically motivated premise that a buyer and seller must have a relationship, a "link," to exchange goods. Networks - buyers, sellers, and the pattern of links connecting them - are common exchange environments. This paper develops a methodology to study network structures and explains why agents may form networks. In a model that captures characteristics of a variety of industries, the paper shows that buyers and sellers, acting strategically in their own self-interests, can form the network structures that maximize overall welfare.

The development of the banking sector as well as the recent macro-economic stability in Bulgaria fostered credit. There are signs of a credit boom and all the conditions for the development of credit to small and medium enterprises are met. Such a boom is the root of the future development of Bulgaria: with more than 99% of small and medium enterprises, representing 34.2% of the value added, and 61.1% of the turnover in private enterprises, they are the essential entrepreneurial force in the country. The access of these firms to financial resources is the condition for the development of businesses through individual efforts on the market. The profitability of loans to big firms, the uncertainty of loans to small enterprises, and the inefficiencies of the legal systems are usually pinned down as the sources of the difficulties of entrepreneurs to find financial resources. Such a situation may hamper the development of the private sector in Bulgaria but also, as this article will show, maintain a part of the private sector in the informal economy. This study aims at showing that the sources of credit for SMEs in Bulgaria are largely dominated by informal forms of credit – i.e. in the family, among friends, etc. – and that the intervention of bank loans comes later in the life cycle of businesses. Networks are thus the root of credit to SMEs. If loans are not available through the banking system, individuals tend to look for loans through their network of relatives and friends. Using a hypothesis formulated by Black and Strahan (2002) and adapting it to the case of Bulgaria we show that it is the type of information required by the lender that influences the sources of credit used. Using a sample of 149 firms in Sofia representative of the national sector composition of Bulgaria, we studied the sources of credit of entrepreneurs and their opinion of the accessibility and efficiency of these various sources.

We study informal insurance within communities, explicitly recognizing the possibility that subgroups of individuals may destabilize insurance arrangements among the larger group. We therefore consider self-enforcing risk-sharing agreements that are robust not only to single-person deviations but also to potential deviations by subgroups. However, such deviations must be credible, in the sense that the subgroup must pass exactly the same test that we apply to the entire group; it must itself employ some self-enforcing risk-sharing agreement. We observe that the stability of subgroups is inimical to the stability of the group as a whole. Two surprising consequences of this analysis are that stable groups have (uniformly) bounded size, a result in sharp contrast to the individual-deviation problem, and that the degree of risk-sharing in a community is generally non-monotonic in the level of uncertainty or need for insurance in the community.

In this paper we propose an interpretation of the current Global Financial Crisis which emphasizes sectoral dislocation following localized technical change in the presence of barriers to labor mobility. This tale is reminiscent of a similar tale concerning the Great Depression. In the 30s technical change was localized in agriculture, where income fell because rising productivity could not be offset by a shrinking labor force due to the costs of moving out of agriculture for unemployed workers, inelastic demand for agricultural output meant that as output increased income declined. As individual incomes fell below the level necessary to finance the transition to manufacturing, excess labor became trapped in agriculture, reducing wages and exacerbating the rise in output. Shrinking incomes in agriculture reverberated on the other sectors, mainly manufacturing causing a large depression. Nowadays, it is manufacturing that plays the role of epicenter of technical change. Falling incomes in manufacturing yield a lack of demand for goods produced in the rest of the economy, namely the service sector. This may be the deep rooted cause of the long lasting slump and the painfully slow recovery.

Using detailed data on gifts, loans, and asset sales, this paper investigates how rural Filipino households deal with income and expenditure shocks. We find that shocks have a strong effect on gifts and informal loans, but little effect on sales of livestock and grain. Mutual insurance does not appear to take place at the village level; rather, households receive help primarily through networks of friends and relatives. Certain shocks are better insured than others. The evidence is consistent with models of quasi-credit where risk is shared within networks through flexible, zero-interest informal loans combined with pure transfers.

This paper considers the formation of risk-sharing networks. Following empirical findings, we build a model where pairs form links, but a population cannot coordinate links. As a benchmark, individuals commit to share monetary holdings equally with linked partners. We find efficient networks can (indirectly) connect all individuals and involve full insurance. But equilibrium networks connect fewer individuals. When breaking links, individuals do not consider negative externalities on others in the network. Thus identical individuals can end up in different positions in a network and have different outcomes. These results may help to explain empirical findings that risk-sharing is often asymmetric.

This paper proposes an explanation of the configuration of mutual insurance groups and of the quality of insurance within each group on the basis of two types of transaction costs: “association” costs in establishing links with insurance partners and “extraction” costs in using these links to implement insurance transfers. We show that optimal insurance arrangements can range from full insurance to autarky within risk pools that span a range of possibilities from cluster formation to community-wide risk sharing. We use a unique data set on canal water trading among households in Pakistan to illustrate the effects of transaction costs in localizing and limiting exchange.
