SNAP and Paycheck Cycles

It is well documented that individuals do not spend the Supplemental Nutrition Assistance Program (SNAP) benefits smoothly over the month after receipt. Rather, recipients spend a disproportionate share of benefits at the beginning of the benefit month. This has costs for recipients and stores. There is also evidence that other income streams, such as Social Security and paychecks, are not spent smoothly. The presence of these other income streams may bias estimates of the effects of this SNAP cycle on consumption for working SNAP beneficiaries and those who receive other government benefits. We use data from United States Department of Agriculture's National Household Food Acquisition and Purchase Survey to explore how the SNAP cycle is affected by accounting for these other income streams. We find suggestive evidence that the cycle is more pronounced for workers who are paid on a weekly or monthly basis, but little evidence that cycles in other income streams mitigate or exacerbate the SNAP cycle.     

Internal Information Quality and the Sensitivity of Investment to Market Prices and Accounting Profits

We ask whether the quality of internal information matters for investment decisions. We predict that investment is more sensitive to internal profit signals and less sensitive to external price signals when managers have higher‐quality internal information. Consistent with recent theoretical and empirical research, we proxy for internal information quality using observable information properties. We find that the sensitivity of investment to profitability is increasing, while the sensitivity of investment to market‐to‐book is decreasing in internal information quality. Our focus on internal information and decision making offers new and unique insights on the importance of information quality and complements the growing literature on the role of external reporting quality in reducing financing frictions.

Cost Efficiency of International Tourist Hotels in Taiwan: A Data Envelopment Analysis Application

This paper uses the data envelopment analysis approach to measure cost, allocative and overall technical efficiencies of international tourist hotels (ITHs) in Taiwan during 1997–2006. There are three outputs, three inputs, three input prices and four environmental variables in the empirical model. The cost inefficiency of these hotels is from overall technical inefficiency. International tourist hotels in Taiwan have an average efficiency of 57%. Chain systems, non-metropolitan areas and occupancy rate have significantly positive impacts on all efficiency scores of Taiwan's ITHs. The distance from the nearest international airport significantly worsens their efficiency scores.     

Bundling attractions for rural tourism development

Tourism is often regarded as a viable solution to economic crisis, especially for remote areas without many development options. While many tourism destinations have strong cultural or heritage assets, not all destinations have primary attractions that can bring visitors to the region. Rather than developing special interest “themes”, rural areas that do not have enough of any one type of tourism resource to act as a primary draw may consider bundling different attraction types to increase visitation. The purpose of this study is to investigate the preferences of visitors to secondary heritage sites and explore the relationship between heritage tourism and alternative, non-heritage activities in rural areas. Findings revealed that motivation to visit small-scale heritage sites consisted of two dimensions: learning and recreation. The two motivational dimensions influenced visitors’ interest in different heritage attractions and likelihood of visiting heritage tourism “scenarios”. As for alternative activities, there was a cluster of “popular” activities that were enjoyed by both learning-oriented and recreation-oriented respondents, but recreation-oriented visitors were more interested in nature-based activities and sport-related activities than learning-oriented visitors. Findings can help rural communities improve secondary attractions and diversify their tourism product by bundling heritage attractions with non-heritage activities.     

Building up a B2B e-commerce strategic alliance model under an uncertain environment for Taiwan's travel agencies

E-travel agencies adopt B2B strategic alliances in order to strengthen their competitive advantages in the e-commerce travel market and because they are an effective tool to gain wider sustainable gains. External environmental and internal organizational factors impacting the success of strategic alliances model are themselves a crucial issue. This study uses multiple methods to collect data from multiple sources and uses qualitative and quantitative surveys. A two-stage research design is adopted to explore the present strategic alliances between Taiwan's wholesaler e-travel agencies and retailer sub-agencies. The results provide an in-depth understanding into the B2B e-commerce strategic alliance model. According to this research, Taiwanese e-travel agencies consider three external environment uncertainties, five internal organization motivations, five partner selection criteria, and two performance measurements of alliance strategies. Finally, the paper proposes an optimal B2B e-commerce strategic alliance model that matches the essential development needs of B2B e-commerce and overcomes the environmental uncertainties.

星载合成孔径雷达数据压缩

星载遥微波成像雷达的观测区域广阔，图像分辨清度高。所以，星载遥感微波成像雷达具有数据率高、数据量大的特点。这就对遥感数据的传输和存储提出了较高的要求。本文提出采取数据压缩方法，在不降低测绘带宽和测绘精度条件下，降低遥感雷达数据率和数据量，从而降低对数据链和星上数据存储设备的要求。本文还对遥感雷达原始数据压缩和遥感雷达图像数据压缩优缺点进行了比较，提出了采用遥感原始数据压缩的建议。最后，对遥感雷达原
