  • 1. Background

! Our life is full of risks! ! A disaster: An unforeseen large negative event which overwhelms local

  • capacity. There are three types:

" The natural disasters 1) Hydro-meteorological disasters: Floods, storms (typhoons), and droughts 2) Geophysical disasters: Earthquakes, tsunamis and volcanic eruptions 3) Biological disasters: Epidemics and insect infestations. " The technological disasters 1) Industrial accidents: Chemical spills, collapses of industrial infrastructures 2) Transport accidents: By air, rail, road or water means of transport. " Manmade disasters 1) Economic crises: Growth collapse, hyperinflation, and currency crisis 2) Violence: Terrorism, civil strife, riots, and war.

  • 2. Risk Management (Mitigation) and Risk Coping Strategies

! Household risk management strategies: Activities for mitigating risk and reducing income instability before the resolution of uncertainties (Walker and Jodha, 1986; Alderman and Paxson, 1992). " Ex ante management is cost effective against disasters: ! Investments in earthquake-proof house, insurance contracts, and access to the early-warning system " Yet, such strategies are often difficult by nature because (natural) disasters are typically unforeseen and rare events.

  • 2. Risk Management and Risk Coping Strategies

! Household risk-coping strategies: Ex post strategies to maintain consumption (livelihood) [Alderman and Paxson (1992)]. !" To use market mechanisms: ! Credit markets to reallocate future resources to today’s consumption ! Insurance market transactions (need ex ante contract though) ! Ex post labor market participation o use returns to human capital #" Self-insurance mechanisms ! To reduce consumption expenditure with maintaining total calorie intakes. ! To use accumulated financial and physical assets (precautionary saving). $" Non-market insurance mechanisms ! To receive public and private transfers. ! Against unexpected natural disasters, ex post risk-coping will be indispensable

  • 2. Risk Coping Strategies I: The Asian Financial Crisis

! During the currency crisis in Indonesia, Korea, Thailand and Mexico, consumption reallocation was an important coping strategy ! In Korea, extended credit was also important but not enough. The likelihood of facing credit constraints increased significantly [Kang and Sawada (2003); around 2,000 panel households]

Changes in per capital consumption in Korea Aug 1996 – July 97 Aug 1997 – July 98 Change rate (%) mean (std. error) mean (std. error) Expenditures for luxuries (cultural& activities, entertainment, dining out, and durable goods) 147.25 (333.75) 53.98 (86.36)

! On May 12, 2008, the Great Sichuan Earthquake occurred, with the epicenter Wenchuan County at Sichuan Province of China. " 69,197 people dead, 18,222 missing, and left about 4.8 million people homeless " In March 2009, we conducted a survey with 2,000 respondents out of around 30,000 people in a temporary housing district at Mianzhu County [Sawada and Li, 2010].

! On September 25, 2006, super typhoon Milenyo hit Luzon Island. " 496,325 homes were totally or partially destroyed. " 127 deaths, 323 injured, and 45 missing. " In January-April 2007, we conducted our own survey of 400 households in a village by the (East) Laguna Lake near Los Banos (Sawada et al., 2009)

! Formal insurance against natural disasters are limited. " Insured losses arising from natural disasters: ! Sawada and Shimizutani (2007; 2008): the overall ineffectiveness of formal and informal insurance mechanisms against the Kobe earthquake. " Formal tests of consumption risk sharing hypothesis (RSH). " Sensitivity of consumption (livelihood) change systematically related to damages " Similar tests were conducted for other disasters (Korean crisis and Vietnamese AI)

Tests of risk sharing: Distribution of households by extent of change in consumption and extent of damage (%)

Damage degree Consumption (livelihood) changed substantially or slightly (%) No change (%) Major damage 80.22 19.78 Moderate damage 73.31 26.69 Minor damage 60.65 39.35 Home No damage 50.48 49.52

  • 4. How to handle aggregate risks? Index Insurance

! Potentially, micro-credit programs can play a role of disaster insurance through a flexible repayment system [For Bangladesh, Shoji (2010) JDS] ! Index insurance contracts are written against specific aggregate events such as drought or flood defined and recorded at a regional level [Hazell (2003); Morduch (2004); Lilleor, Gine, Townsend, Vickery (2005); Skees, Varangis, Larson and Siegel (2006)]. " Can cover the aggregate events " Divisible, so affordable and accessible even to the poor " Easy to implement and privately managed " Free from moral hazard, adverse selection, and high transaction costs that have plagued traditional agricultural insurance contracts such as crop insurance schemes. ! Weather-based Index Insurance in LDCs " Rainfall insurance in India and Malawi [Gine and Yang (2009) JDE] " Famine index insurance [Chantarat, et al. (2007) AJAE] " Livestock based index insurance (ILRI, Nairobi) " WFP in Ethiopia

  • 4. How to handle aggregate risks? Index Insurance

! Major constraints to design index type insurance against natural disasters. " A “rare” event; making it difficult to design actuarially fair insurance and to set appropriate premium because obtaining historical data on natural disasters pattern is hard [Morduch (2004)]. " The poor may find it difficult to recognize the value because natural disasters are

  • ften characterized by unforeseen contingencies and because the poor often are

myopic with high time discount rates [Pender (1996)]. Human beings tend to ignore rare bad events [Camerer and Kunreuther (1989)]. " The existence of the “basis risk” also deters demand [Morduch (2004); Hazell (2003)]. " The insurers need international reinsurance markets. Yet, reinsurance markets and trades of catastrophe (CAT) bonds are still thin.

Nakata, Sawada, and Tanaka (2009): In 2008, hypothetical questions on AI, flood (FL), and drought index insurance in Vietnam with 2,000 respondents of VHLSS 2006 " A past experience dramatically increases probability assessment of the event (10 and 100 times for AI and FL) and WTP for the insurance (30% and 50% for AI and FL)

  • 4. How to match aid inflows and demand without moral hazard?

! In matching of emergency demands and massive proliferations of aid supply under imperfect information and uncertainties may create moral hazard problems: " Targeting failure: wrong people are targeted or right targets are excluded " Moral hazard: Even under “tagged” targeting interventions, there are perverse incentives to change their characteristics to gain eligibility, e.g. “Tsunami marriages” " Transaction costs: Timely matching will be very costly. The July 2006 report of Tsunami Evaluation Coalition (TEC) found: 1) Tsunami victims received US$7,100 on average 2) Relief is not necessarily given on the basis of need 3) Relief is allocated in response to political pressure or to the donating public. ! The role of social capital or community-based management (CBM)? " CBM will ease the imperfect information problems and enable the beneficiaries to amplify their voice in policymaking and to strengthen the incentives for providers to serve effectively. " WB allocated $7 billion in 2003 to CBM related projects ($3 billion in 1996)

Finally -

・ Against disasters as unforeseen contingencies, ex post risk coping strategies and effective market mechanisms (insurance, credit, labor etc.) are the key. ・ Yet, formal/informal insurance mechanisms are largely ineffective against disasters right now. ・ So, new innovative ideas such as index insurance and community-based management should be elaborated on. ・ Evidence-based policies are indispensable: Continued data collection and evaluation of the policies (before &) after each disaster will be important.
