Reproductive investment and seedling survival of the mast-fruiting rain forest tree, Microberlinia bisulcata A. chev

In the southern part of Korup National Park, Cameroon, the mast fruiting tree Microberlinia bisulcata occurs as a codominant in groves of ectomycorrhizal Caesalpiniaceae within a mosaic of otherwise species-rich lowland rain forest. To estimate the amount of carbon and nutrients invested in reproduction during a mast fruiting event, and the consequential seed and seedling survival, three related field studies were made in 1995. These provided a complete seed and seedling budget for the cohort. Seed production was estimated by counting woody pods on the forest floor. Trees produced on average 26,000 (range 0-92,000) seeds/tree, with a dry mass of 16.6 kg/tree. Seeds were contained in woody pods of mass 307 kg/tree. Dry mass production of pods and seeds was 1034 kg ha(-1), equivalent to over half (55%) of annual leaf litterfall for this species, and contained 13% of the nitrogen and 21% of the phosphorus in annual leaf litterfall. Seed and young-seedling mortality was investigated with open quadrats and cages to exclude vertebrate predators, at two distances from the parent tree. The proportion of seeds on the forest floor which disappeared in the first 6 wk after dispersal was 84%, of which 26.5% was due to likely vertebrate removal, 36% to rotting, and 21.5% to other causes. Vertebrate predation was greater close to the stem than 5 m beyond the crown (41 vs 12% of seeds disappearing) where the seed shadow was less dense. Previous studies have demonstrated an association between mast years at Korup and high dry-season radiation before flowering, and have shown lower leaf-litterfall phosphorus concentrations following mast fruiting. The emerging hypothesis is that mast fruiting is primarily imposed by energy limitation for fruit production, but phosphorus supply and vertebrate predation are regulating factors. Recording the survival of naturally-regenerating M. bisulcata seedlings (6-wk stage) showed that 21% of seedlings survived to 31 mo. A simple three-stage recruitment model was constructed. Mortality rates were initially high and peaked again in each of the next two dry seasons, with smaller peaks in the two intervening wet seasons, these latter coinciding with annual troughs in radiation. The very poor recruitment of M. bisulcata trees in Korup, demonstrated in previous investigations, appears not to be due to a limitation in seed or young-seedling supply, but rather by factors operating at the established-seedling stage.

Land acquisition, investment, and development in the Lao coffee sector: Successes and failures

Despite the increasing acknowledgment of scholars and practitioners that many large-scale agricultural land acquisitions in developing countries fail or never materialize, empirical evidence about how and why they fail to date is still scarce. Too often, land deals are portrayed as straightforward investments and their success is taken for granted. Looking at the coffee sector in Laos, the authors of this article explore dimensions of the land grab debate that have not yet been sufficiently examined. Coffee concessionaires in southern Laos often fail to use all of the land granted them and fail to produce high yields on the land they do use. Thus, the authors challenge the often-assumed superiority and effectiveness of large-scale versus small-scale production, specifically the argument that they modernize agricultural production and optimize land use. They argue that examining failed investments is as important as studying successful ones for understanding the implications of the land grabbing phenomenon for social, economic, and environmental outcomes. Knowledge about the scale of “failed land deals” provides important motivation for national governments to close the gap between intentions and actual outcomes. This article engages with the current debate on quality of investment and challenges the approach of employing land concessions as a vehicle for economic development in the Lao coffee sector and in other sectors and countries.

Technology, Investment, and Economic Fluctuations

Since 1854, the United States has experienced 32 business cycles. While the average length of these cycles (trough-to-trough) has been 51 months, there has been significant variation across different subperiods. This paper attempts to explore the relationship between capital accumulation, technology accumulation, and the business cycle.

Human Capital Investment and Poverty Reduction over Generations: A Case from the Rural Philippines, 1979-2003

This paper attempts to identify a pathway out of poverty over generations in the rural Philippines, based on long-term panel data spanning for nearly a quarter of a century. Specifically, it sequentially examines the determinants of schooling, subsequent occupational choices, and current non-farm earnings for the same individuals. We found that an initial rise in parental income, brought about by the land reform and the Green Revolution, among other things, improves the schooling of children, which later allows them to obtain remunerative non-farm jobs. These results suggest that the increased agricultural income, improved human capital through schooling and the development of non-farm sectors are the keys to reducing poverty in the long run. It must be also pointed out that the recent development of the rural non-farm sector offers ample employment opportunities for the less educated, which also significantly contributed to the poverty reduction.

Trade, Foreign Investment and Myanmar's Economic Development during the Transition to an Open Economy

Throughout the 1990s and up to 2005, the adoption of an open-door policy substantially increased the volume of Myanmar's external trade. Imports grew more rapidly than exports in the 1990s owing to the release of pent-up consumer demand during the transition to a market economy. Accordingly, trade deficits expanded. Confronted by a shortage of foreign currency, the government after the late 1990s resorted to rigid controls over the private sector's trade activities. Despite this tightening of policy, Myanmar's external sector has improved since 2000 largely because of the emergence of new export commodities, namely garments and natural gas. Foreign direct investments in Myanmar significantly contributed to the exploration and development of new gas fields. As trade volume grew, Myanmar strengthened its trade relations with neighboring countries such as China, Thailand and India. Although the development of external trade and foreign investment inflows exerted a considerable impact on the Myanmar economy, the external sector has not yet begun to function as a vigorous engine for broad-based and sustainable development.

U.S.-Israel Foreign Direct Investment and Terrorism. ACES Working Paper No. 9, 2007

The Israeli economy has been subjected to a continuous flow of terror since its creation. The focus of our study is how terrorism's impacts the level of production of the high-tech sector. The two main objectives and novelties of the paper are: First our paper can be a major contribution to as yet a new subfield in applied microeconomics attempting to measure the impact of terror on economic issues like FDI and Industry output in general and that focused on the High-Tech industries. Second our research is designed to help us understand the impact of terror news, especially on U.S citizens' reactions to terror in Israel. Our terror variable isn't how many bodies or but how many negative articles regarding terror there are in leading American news paper. We focus on the volatility clustering of terror information arrivals in major US financial papers and its impact on high-tech production and FDI to Israel.

Social Investment and State Capacity. CEPS Working Document No. 419/February 2016

This paper looks at the difference between the levels and nature of social policy expenditure in northern and northwest European countries and the countries of southern, central, and eastern Europe, and examines the relationship between social investment and state capacity in these country groupings. The authors show that southern and eastern countries have a much greater preference for ‘compensating’ rather than ‘capacitating’ social policy spending. Furthermore, the state capacity in these countries is lower, which generates less state revenue. Based on these observations they conclude that low state capacity and low state revenue go hand in hand with the preference for capacitating social policies, as these policies involve less delegation and discretion than social investment policies. This paper shows that high state capacity is probably a necessary precondition for effective social investment policies, although some limited alternative paths do exist.

Trade Policy, Investment and Migration: The Liberalisation Paradigm

Presentation by Thomas Cottier & Charlotte Sieber-Gasser prepared for the Markets for Migration and Development (M4MD) Conference, Bern, 13-15 September 2011. This presentation is part of Session 1 "Why Trade, Development and Migration?" of the M4MD conference, which was one of the thematic meetings held in the context of the 2011 Global Forum on Migration and Development (GFMD) chaired by Switzerland. Session 1 seeked to understand to what extent international trade and foreign direct investment drives migration and why states find it more difficult to liberalise the trans‐boundary movement of persons than to liberalise cross‐border trade in goods and services. One discussed aspect was why globalisation, trade liberalisation and FDI can lead not only to more, but also to less migration and what the corresponding effects on development would be. This Session provided a timely opportunity to broaden the perspective on international migration and explore the interaction between migration, development and trade policymaking.
