Household history,SNAP participation,and food insecurity

Food security in an important public policy issue. In 2015, approximately 1 in 8 U.S. households experienced food insecurity at some point in the year. Low-income families are at higher risk for food insecurity than other families, and these families may also face higher levels of disruption (e.g., moves, loss of income, or individuals entering or leaving the household) than other families. I use data from the Survey of Income and Program Participation to explore the relationship between food insecurity, the household’s history during the previous year, and SNAP participation. The results indicate that a number of aspects of the household’s recent experience including negative income shocks, moves, and both increases and decreases in household size increase the probability of being food insecure while SNAP participation is estimated to reduce the probability of being food insecure.     

Industrial buying during the coronavirus pandemic: A cross-cultural study

With the onset of the 2020 coronavirus pandemic, industrial suppliers are increasingly challenged to close their open sales opportunities and keep generating business. Against this backdrop, the authors of this study investigate which offerings industrial customers are most likely to purchase as the pandemic progresses. Drawing on positive decision theory and empirically investigating 31,353 sales opportunities across 57 countries, the authors show that the coronavirus pandemic significantly decreases industrial customers' purchase probability, especially for high-priced offerings. In countries with low uncertainty avoidance and strong long-term orientation (e.g., China, India, Singapore), purchase probability is less affected by the pandemic. The coronavirus pandemic even increases purchase probability for offerings with low prices in countries where cultures are simultaneously uncertainty-avoidant and short-term oriented (e.g., Argentina, Brazil, Mexico). This is presumably because customers safeguard their operations in the face of impending supply shortages. Consequently, this helps suppliers focus on the right sales opportunities to secure their business during exogenous global shocks such as the coronavirus pandemic.     

Consumers’ response to the EU Quality policy allowing for heterogeneous preferences

Using dry-cured ham as an anchor product, consumers’ preferences for EU Quality Certification schemes, region of origin and price have been investigated with conjoint analysis. In order to achieve this aim, a mixed rank-ordered logit which allows for the investigation of heterogeneous preferences and their sources has been estimated. In particular, we have analysed to what extent consumers’ socio-demographic traits affect their price-sensitiveness and whether consumers’ sensory (hedonic) valuations and attitudes towards ham with a Protected Designation of Origin (PDO) affect the preferences for specific attributes. Results show that consumers with a low-medium age and income are more price sensitive. Consumers more inclined sensorially towards the regional specialty (with or without PDO) are more likely to purchase this product, and consumers with a more favourable attitude towards PDO ham are also more prone to purchase cured ham with quality certification. Findings also suggest that although the PDO scheme attracts a segment of consumers, the origin by itself is still a more powerful signal of quality, and more specifically the region of origin.     

The Insolvent Thrifts of 1982: Where Are They Now?

In 1982, 237 thrifts were GAAP (Generally Accepted Accounting Principle) insolvent. By 1987, 92 of these were either merged or closed and 77 remained insolvent. The remaining 68 were GAAP solvent with an average GAAP-to-total-assets ratio of 5.6%. The purpose of this paper is to identify the factors that affected the probability of solvency for the 1982-insolvent thrifts over the period 1983–1987.
To identify these factors, the probability of insolvency is modeled in each year between 1983 and 1987 using logistic regression. Because a thrift can earn its way out of insolvency or raise outside capital, the probability of solvency is a function of the infusion of outside capital along with balance sheet and income statement ratios reflecting the thrifts earning ability. The only variable consistently significant in each year is the variable reflecting the raising of outside capital.     

Price Premium and Foreclosure Risk

Many previous studies identify loan, property, borrower and environmental factors that impact the probability of foreclosure. Implicit in these studies is the assumption that the property was purchased at fair value. We question this assumption based on several empirical findings regarding property value uncertainty. In contrast to previous research, we explicitly quantify the price premium from a hedonic pricing model. Using a comprehensive database of real estate transactions in Singapore during 1989–2000, we document a price premium associated with properties that are subsequently foreclosed based on actual sales transactions. In addition, we find that the premium paid at purchase significantly increases the probability of foreclosure. These results are robust and continue to hold after controlling for other property-specific factors, time-varying macroeconomic conditions, alternative model specifications and definitions of price premium.     

Anticipated Growth and the Specification of Debt in Real Estate Value Models

Standard value models for investment real property do not distinguish between current income and future growth in estimating the probable level of debt financing. Analysis of loan commitment data from 1971–1981 suggests that this was not a proper assumption during that period. Consistent with recent models from the literature of the firm, the portion of the value of investment properties attributable to anticipated growth apparently supported less dept than did current income.     

ADVERSE SELECTION IN ELECTRONIC MARKETS: EVIDENCE FROM ONLINE STAMP AUCTIONS

We analyze adverse selection costs in online stamp auctions, based on a comparison of prices on eBay with those of matched stamps at a specialty stamps auction site in the U.S., Michael Rogers, Inc. (MR), which we know a priori has low quality uncertainty. We find that buyer prices are 10–15% lower on eBay as compared to MR, and the price difference, increases with the value of the stamps. Consistent with this adverse selection discount we find that the seller reputation mechanism on eBay has an economically modest, although statistically significant, effect on auction price and probability of sale.     

Income and Appraised Values: A Reexamination of the FRC Returns Data

This paper compares the income of those office properties that are included in the FRC index, with the appraised values that are used to determine the index's appreciation component. We find that the appraised value of the portfolio was a constant multiple of its current income, over the 1978–1988 period. This seems at odds with what modern valuation theory would suggest, since both nominal interest rates and several measures of real rates varied widely over the sample. An alternate interpretation of our results is that the appraised values were based on a set of expectations about future income growth, that turned out over the period, to be continually at odds with respect to actual income.

农村劳动力流转、粮食商品化程度对粮食主产区农户的农机购置行为的影响分析——基于全国587户粮农数据

利用全国587户粮农数据,通过单因素相对影响比率与Logit模型研究了粮食种植户农机购置行为的影响因素。研究结果表明,外出劳动力数与粮食收入比重对农户购置农机具具有显著的负向激励;粮食生产商品化程度以及粮食直补政策对农户购置农机具有显著的正向激励;耕地面积越大、耕地细碎化程度越低则农户购置农机具的倾向越强;粮食主产区农户的农机购置程度显著较高,而粮食主销区则显著较低;小麦种植户的农机购置程度显著较高,而水稻种植户则显著较低。     

Nile perch and the hungry of Lake Victoria: Gender,status and food in an East African fishery

Lake Victoria supports Africa’s largest inland fishery, and its most valuable product is the Nile perch, much of which is exported. This has given rise to arguments claiming a direct linear relationship between perch exports and disturbingly high rates of malnutrition along the lake’s shores. In this paper, we argue that this argument is seriously flawed for it is unable to explain how it is that the income from the Nile perch fishery fails to translate into a well-fed riparian population. We draw on field work carried out in 2001 that (a) set out to establish exactly how much malnutrition there was on the lake’s shores; and (b) sought to identify what happened to the income the fishery generates. We argue that because men control much of the fishery, and women are held responsible for the upkeep of their families, little of this income makes its way back into the households of the region, giving rise to the levels of malnutrition we observed.     

Product Cue Usage in Two Asian Markets: A Cross-Cultural Comparison

In this paper, we report cross-cultural differences in the use of intrinsic and extrinsic product cues (physical quality, design, brand name and price) on consumers' evaluations and purchase intentions for an apparel product in Shanghai, China and Seoul, South Korea. There were some differences in Chinese and Korean consumers' use of these cues in assessing the quality, value and purchase intentions; however, differences were not extensive. Consumers in both countries relied heavily on price acceptability to determine the value of the product; however, it was used to a greater extent among Chinese consumers to determine value. Our findings revealed that design was another intrinsic product attribute that impacts product evaluations and purchase decisions for both Chinese and Korean consumers. However, design was a stronger predictor of purchase intentions among Korean consumers. Brand name was not a strong cue in product evaluations for consumers in either country, although it was a significant predictor of value perceptions among Chinese consumers.     

R&D investment,business performance,and moderating role of Guanxi: Evidence from China

Conventional wisdom posits that a long-term orientation with important partners such as key suppliers and clients is essential for superior performance. This study critically examines this business tenet by studying the relationship between duration of partnerships with major suppliers and clients and company performance. Based on a dataset comprising over 10,000 Chinese manufacturing firms obtained through a probability sampling procedure, results show that relationship duration with major clients not only has a direct, negative effect on total income (sales), but also has a negative moderating effect on the association between research & development (R&D) and total income. However, relationship duration with major suppliers has a positive moderating effect on the association between R&D and total profits. Furthermore, relationship with government has a positive effect on total income, and it also has a negative moderating effect on the R&D-performance chain. Managerial and research implications are also discussed.     

Housing Costs and the Elderly

Estimates are made of changes in average housing costs and average family incomes for non-moving elderly homeowners and renters over the period 1972–80. Findings suggest that: rental costs are higher in each time period than are homeownership costs; evidence of serious deterioration in affordability of housing is weak, when looking at aggregate price/income ratios; and it is clear that elderly renters are more seriously disadvantaged in housing affordability than are elderly homeowners at every time period.     

Direct Labor Market Effects of Unemployment Insurance

It has been established that relatively high income families receive a disproportionately large share of UI benefits. Little information on the distribution of costs by income class is available, but it is quite possible that the upper income groups may also bear a disproportionately large share of the costs. More empirical research is needed before the redistributive effects of UI can be known with any degree of confidence. There is little argument about the desirability on income mainlenance grounds of extending Unemployment insurance benefits in a recessionary period, all other things being equal. U1 is quite efficient as an income maintenance tool for covered workers. With respect to the unemployment problem, though, it is feared by some that the program goes too far in maintaining the incomes of covered workers, and as a result any extension of UI benefits will aggravate the unemployment problem. The evidence presented here suggests that fears of a major increase in unemployment as a result of such changes are largely unwarranted. However, extended UI benefits would appear to have some small, nontrivial adverse impact on unemployment. Finally, it seems that UI's income distributional impact has been portrayed unjustly as pro-rich. It may be that income is transferred through the UI system from the relatively well-to-do to the relatively poor. There is no scientific way of bringing these considerations to bear in deciding whether or not to restructure the unemployment insurance system. This question can be answered only by invoking fundamental value judgments to decide how sociely would be better off, and I would not presume here to offer my own. This paper will have served its purpose if it has provided the basis for a more informed decision.     

Case Study: Model for Economic Lifetime of Drilling Machines in the Swedish Mining Industry

The purpose of this article is to develop a practical economic replacement decision model to identify the economic lifetime of a mining drilling machine. A data-driven optimization model was developed for operating and maintenance costs, purchase price, and machine resale value. Equivalent present value of these costs by using discount rate was considered. The proposed model shows that the absolute optimal replacement time (ORT) of a drilling machine used in one underground mine in Sweden is 115 months. Sensitivity and regression analysis show that the maintenance cost has the largest impact on the ORT of this machine. The proposed decision-making model is applicable and useful and can be implemented within the mining industry.     

The impact of firm introductory strategies on consumers' perceptions of future product introductions and purchase decisions

In this research, we develop and test a model of the consumer's decision to immediately purchase a technologically advanced product or to delay such a purchase until a future generation of the product is released. We propose that for technologically advancing products, consumers consider both performance lag (how far behind am I now) and expected performance gain (how far ahead will I be if I wait to buy a future expected release) in their purchase decisions. Furthermore, we hypothesize that a firm's past product introductory strategy can significantly influence consumer perceptions of performance lag, performance gain, and the rate at which a product is advancing technologically. We also propose that these perceptions of lag, gain and rate of technological change influence purchase action and ultimately determine whether or not a consumer will delay or immediately purchase a firm's current technological offering. We investigate the above relationships by introducing a model of consumer purchase behavior that incorporates the effects of a firm's frequency and pattern of next generation product introduction, and test the impact of different introductory strategies on performance lag, gain, rate of change perceptions, and purchase action. In our first study we test our model in a monopolistic setting and show that, holding all else fixed, infrequent product upgrades and/or increasing intergenerational release times result in consumers perceiving larger performance lags and gains. We also show that, holding all else fixed, consumers with larger performance lags and/or gains are less likely to delay their purchases of the currently best available product. In our second study we test our model in a competitive setting and show that, holding all else fixed, a firm's past pattern of new product introduction can influence consumers' perceptions of the firm's product's rate of technological change. We also find that consumers are more likely to purchase products which they perceive to have higher rates of technological change. The key insight from this research is that firms have a strategic tool at their disposal that has been overlooked—the pattern of introduction of next generation products. Our findings suggest that a change in the frequency and/or pattern of introduction, in and of themselves, can influence consumers' perceptions of future product introductions, and ultimately influence their purchase actions. Specifically, we demonstrate that by better understanding consumers' purchase timing decisions, firms may be able to induce purchase on the basis of introductory frequency and pattern alone. Additionally, we demonstrate that by strategically managing consumer expectations of future product introductions, firms may be able to decrease the purchase likelihoods of competing products. Implications of our research and its application to the pattern and timing of preannouncements for new products are also explored.     

Dynamics of the Greenbelt Amenity Effect on the Land Market—The Case of Seoul's Greenbelt

Seoul's greenbelt has been maintained for twenty years with little change, although Seoul has grown rapidly. Therefore, Seoul's greenbelt is interesting to examine for the dynamic impacts of a greenbelt regulation in a growing city. These impacts are examined in this article which also exploits a unique time series of Seoul property values (1970–1989). The results show that the amenity value of Seoul's greenbelt is quite high. However, the marginal value of greenbelt accessibility has been decreasing since 1980, in notable contrast to earlier years. A simple welfare analysis demonstrates that as the city grows, the greenbelt eventually loses its efficiency as a policy tool, even though earlier it may have achieved economic efficiency.

EXPLAINING VARIANCE IN THE PERFORMANCE OF LONG-TERM CORPORATE BLOCKHOLDERS

This study measures and explains variance in the performance of corporations that purchase and hold blocks of stock in other corporations. Results show that following the purchase of between 5 and 50 percent of a target corporation's common stock, blockholder performance improves on average for 15 months. After 3, 7, 11, and 15-month intervals, performance is positively associated with (1) investments in targets that are suppliers or customers, (2) targets that make cross-investments into the equity securities of the blockholder, and (3) a blockholding value ratio that contrasts the value of the blockholding with the value of the blockholder.
