    Hazardousness of place : a new comparative approach to the Filipino past

    Get PDF
    © Ateneo de Manila University. The historiography of the Philippines has been largely bounded by the nation-state, which has defined how its past has been conceived and to whom its peoples are mainly compared. A more transnational environmental history, however, seeks to situate the archipelago within the context of the daily threats that its peoples have to face. This article focuses on the hazardous nature of living in the islands and explores the ways in which Filipinos have adapted to natural hazards as a frequent life experience over time

    Coping with Disaster: The Impact of Hurricanes on International Financial Flows, 1970-2002

    How well do countries cope with the aftermath of natural disasters? In particular, do international financial flows help buffer countries in the wake of disasters? This paper focuses on hurricanes (one of the most common and destructive types of disasters), and examines the impact of hurricane exposure on resource flows to developing countries. Using meteorological data on storm paths, I construct a time-varying storm index that takes into account the fraction of a country's population exposed to storms of varying intensities. Across developing countries, greater hurricane exposure leads to large increases in foreign aid. For other types of international financial flows, the impact of hurricanes varies according to income level. In the poorer half of the sample, hurricane exposure leads to substantial increases in migrants' remittances, so that total inflows from all sources in the three years following hurricane exposure amount to roughly three-fourths of estimated damages. In the richer half of the sample, by contrast, hurricane exposure stimulates inflows of new lending from multilateral institutions, but offsetting declines in private financial flows are so large that the null hypothesis of zero damage replacement cannot be rejected.

    The Philippines: Shadow WTO Agricultural Domestic Support Notifications

    Get PDF
    "The objective of this paper is to review the agricultural trade and domestic policies of the Philippines and to provide an assessment of the types and levels of domestic support relative to the rules of the World Trade Organization (WTO). Changes in trade protection and support in the Philippines, including tariff structure, quantitative restrictions, and domestic support, are discussed and analyzed. The paper also discusses the pattern of public expenditure on agriculture in the Philippines, including major agricultural productivity-enhancing programs. The present structure of protection and support favors the agricultural sector. Trade protection is higher in agriculture relative to manufacturing. There is a quantitative restriction on rice imports and a tariff rate quota in several agricultural commodities. The green box payments and the special and differential treatment constitute the major domestic support for agriculture. These support payments are relatively substantial and will continue to be sizable in the future to support the government's food sufficiency policy. However, the trade-distorting market price support for rice and corn is significantly below the de minimis limit that applies to the Philippines under the WTO Uruguay Round Agreement on Agriculture." from author's abstractPhilippine agriculture, Agricultural support, WTO support, WTO compliance, Notification of domestic support, trade,

    Natural disasters and growth: evidence using a wide panel of countries

    Large natural disasters (LNDs) are ubiquitous phenomena with potentially large impacts on the infrastructure and population of countries, and on their economic activity in general. I examine the occurrence pattern of several types of disasters on a panel of 113 countries and its relationship with economic growth using data ranging from 1960 to 1996. The disasters are earthquakes, floods, slides, volcano eruptions, tsunamis, wind storms, wild fires and extreme temperatures. The country sample is partitioned in two ways: small, medium and large population; and low, medium and high income. The results suggest a heterogeneous pattern of short and long-term impact of LNDs, depending on the per capita GDP, the size of the countries studied and the type of LND. Overall, and contrary to previous research, LNDs appear to have persistent effects on the rate of GDP growth in the period between 1960 and 1996. These effects range from a decrease of 0.9% to an increase of 0.6%, depending on the type of disaster.Natural disasters, catastrophes, growth, foreign aid, panel data

    Natural natural disasters and economic disruption

    Get PDF
    The cost of natural calamities is not limited to direct capital losses. Economies in the wake of severe shocks experience important slowdowns. I construct an exhaustive dataset of objective measures on cyclones and earthquakes worldwide between 1980 and 2006 and complement existing reports on direct damages. I then estimate the amplitude of indirect economic losses in the aftermath of catastrophes. Declared damages accounting for 1% of GDP are associated with a slowdown of .05 to .06 points of GDP growth. The economic slack piles up to .4 points of GDP when I instrument by actual exposure to alleviate censorship issues and declaration biases. This output loss is superior to what would suggest a model of labor frictions and capital losses and points to large business disruptions. Finally, the objective measures happen to be better at predicting the economic slack than estimations from officials.natural disasters ; economic disruption ; declaration biases

    Remittance stability, cyclicality and stabilizing impact in developing countries

    Get PDF
    That remittances are a stable source of external finance seems to have become the received wisdom. In addition, many studies have found remittances to behave counter-cyclically, increasing during crises and times of hardship for the recipient countries. Are remittances reliable macroeconomic stabilizers? To answer this question, the present study examines the stability, cyclicality, and stabilizing impact of remittances in comparison with the same three features for other foreign-exchange inflows, namely foreign direct investment and official development aid. The analysis is performed at the country and regional levels rather than at the aggregate or global level (on which much of the received wisdom rests), because policymakers are concerned with the impact of remittances in their country rather than at the global level. The main findings for 1980-2007 are that in a majority of countries: i) official development aid is more stable than remittances, and remittances are more stable than foreign direct investment; ii) official development aid is counter-cyclical, while remittances are pro-cyclical, although less so than foreign direct investment; and iii) official development aid is stabilizing and remittances are destabilizing, although less so than foreign direct investment. The paper suggests that it is necessary to examine counter-cyclicality separately from the stabilizing impact, as the former does not seem to always imply the latter.Economic Conditions and Volatility,Remittances,Debt Markets,Economic Theory&Research,Emerging Markets

    Using Twitter to Understand Public Interest in Climate Change: The case of Qatar

    Full text link
    Climate change has received an extensive attention from public opinion in the last couple of years, after being considered for decades as an exclusive scientific debate. Governments and world-wide organizations such as the United Nations are working more than ever on raising and maintaining public awareness toward this global issue. In the present study, we examine and analyze Climate Change conversations in Qatar's Twittersphere, and sense public awareness towards this global and shared problem in general, and its various related topics in particular. Such topics include but are not limited to politics, economy, disasters, energy and sandstorms. To address this concern, we collect and analyze a large dataset of 109 million tweets posted by 98K distinct users living in Qatar -- one of the largest emitters of CO2 worldwide. We use a taxonomy of climate change topics created as part of the United Nations Pulse project to capture the climate change discourse in more than 36K tweets. We also examine which topics people refer to when they discuss climate change, and perform different analysis to understand the temporal dynamics of public interest toward these topics.Comment: Will appear in the proceedings of the International Workshop on Social Media for Environment and Ecological Monitoring (SWEEM'16
