Baby Boom, Asset Market Meltdown and Liquidity Trap

A so-called “asset market meltdown hypothesis” predicts that baby boomers’ large savings will drive asset market booms that will eventually collapse because of the boomers’ large retirement dissavings. As good news to baby boomers, our analysis shows that this meltdown hypothesis is fundamentally flawed; and baby-boom-driven asset market booms may not necessarily collapse. However, bad news is that, in the case where meltdowns are about to happen, forward-looking baby boomers’ attempts to escape them will be futile and may lead the economy into a “liquidity trap”.

Entomopathogenic fungi and invasional meltdown

Invasive non-native (alien) species are considered to be one of the greatest threats to biodiversity (Millenium Ecosystem Assessment 2005) through predation, competition, hybridisation or as vectors of disease (Hulme et al., 2009). The movement of peole and goods is increasing the rate of invasive alien species arriving in countries around the globe. A recent inventory of alien species in Europe revealed a figure of 11000 species (Hulme et al., 2009) but it is recognised that this is a first approximation and likely to be an underestimate (Olenin & Didžiulis, 2009). The distinction between native species and alien species is problematic; species have been moving around the world over millennia and the origin of many species is uncertain. It is also evident that many archaeophytes and archaeozoans establish within native communities without detrimental effects on species and ecosystem processes (Pyšek et al., 2005). However, the small proportion of alien species that are problematic (invasive) are both ecologically and economically costly (Hulme et al., 2009). Furthermore, historically species movements have occurred within continents but in recent decades an increasing proportion of alien species are from other continents (Hulme et al., 2009). Alien species originating from within a continent are predicted to be less invasive than those from other continents (Hulme et al., 2009)

Asset meltdown : fact or fiction?

This paper analyzes the relation between demographic structure and real asset returns on treasury bills, bonds and stocks for the G7-countries (United States, Canada, Japan, Italy, France, the United Kingdom and Germany). A macroeconomic multifactor model is used to examine a variety of different demographic factors from 1951 to 2002. There was no robust relationship found between shocks in demographic variables and asset returns in the framework of these models, which suggests that Asset Meltdown is rather fiction than fact

Impact of Global Economic Meltdown on Property Development in Bauchi, Nigeria

The global economic meltdown is a situation in which the economy of a country experiences a sudden downturn brought on by a financial crisis. This global recession was caused by so many factors, thus, inflation rate, exchange rate, interest rate, unemployment rate, etc. This paper examined the impact of the global economic meltdown on property development in Bauchi, Nigeria. Data for the study are mainly primary in the form of questionnaires administered. The study had property development as an endogenous variable while a high-interest rate and unemployment rate as exogenous variables to measure the constructs. Multiple Regression were used to analyze the data. Among the study, findings are that high relationship exists between the two predictor variables (High-Interest Rate & Unemployment Rate) and dependent variable (property Development) where ‘R’ of 0.724 means the correlation is about 72 %; with R2 of 0.052 indicate that 5.2 % correlation, the analysis also depict in coefficient table that high-interest rate has more influence on dependent variable (PD) than unemployment rate. The analysis signified that the impact of the global economic meltdown has a positive effect on the dependent variable. Based on the findings, the study recommended governments and financial institutions intervention to curb the impediment of property development in Bauchi, Nigeria

Reviving Meltdown 3a

Since the initial discovery of Meltdown and Spectre in 2017, different variants of these attacks have been discovered. One often overlooked variant is Meltdown 3a, also known as Meltdown-CPL-REG. Even though Meltdown-CPL-REG was initially discovered in 2018, the available information regarding the vulnerability is still sparse. In this paper, we analyze Meltdown-CPL-REG on 19 different CPUs from different vendors using an automated tool. We observe that the impact is more diverse than documented and differs from CPU to CPU. Surprisingly, while the newest Intel CPUs do not seem affected by Meltdown-CPL-REG, the newest available AMD CPUs (Zen3+) are still affected by the vulnerability. Furthermore, given our attack primitive CounterLeak, we show that besides up-to-date patches, Meltdown-CPL-REG can still be exploited as we reenable performance-counter-based attacks on cryptographic algorithms, break KASLR, and mount Spectre attacks. Although Meltdown-CPL-REG is not as powerful as other transient-execution attacks, its attack surface should not be underestimated.Comment: published at ESORICS 202

The mutational meltdown in asexual populations

Loss of fitness due to the accumulation of deleterious mutations appears to be inevitable in small, obligately asexual populations, as these are incapable of reconstituting highly fit genotypes by recombination or back mutation. The cumulative buildup of such mutations is expected to lead to an eventual reduction in population size, and this facilitates the chance accumulation of future mutations. This synergistic interaction between population size reduction and mutation accumulation leads to an extinction process known as the mutational meltdown, and provides a powerful explanation for the rarity of obligate asexuality. We give an overview of the theory of the mutational meltdown, showing how the process depends on the demographic properties of a population, the properties of mutations, and the relationship between fitness and number of mutations incurred
