Quantifying the socio-economic determinants of sustainable crop production: an application to wheat cultivation in the Tarai of Nepal

This study specifies a procedure to quantify the determinants of sustainable crop production, and applies the method to wheat cultivation in the Tarai of Nepal. Three aspects of sustainability were considered. First, the fertility of the land was found to have deteriorated owing to long-term practices incompatible with soil and drainage conditions. Three-quarters of the farmers had reduced land fertility and for one-third of them the wheat yield was at least 20% lower than for farmers who applied farmyard manure to every crop and adopted a rotation consistent with soil and drainage conditions. Secondly, the study found that it was possible to improve resource-use efficiency in wheat production to give 25% higher production at current levels, type, and quality of farm resources. Resource-use efficiency was significantly related to farm management practices such as crop stand, variety, disease, and land preparation quality, and socio-economic factors such as off-farm job opportunities, poor plot accessibility, and migration. Thirdly, the increasing population pressure on land, decreasing livestock number per cropped area, and diminishing fuel wood sources, significantly reduced farm-based nutrient cycling because farmyard manure had to be used for fuel. This had implications for the higher use of the fossil-based inputs in crop production.     

Exogenous information and input-output updating: An evaluation

Input-output coefficients' intertemporal instability, costs, and time lags involved in the construction of survey-based tables necessitate employment of nonsurvey updating techniques. Analysts, however, may want to include exogenous information in the updating process. The issue, then, is whether this inclusion ameliorates or aggravates the results. This paper attempts to assess the wisdom of incorporating exogenous information into the updating procedure. First, using the naive, RAS, and LaGrangian techniques, the 1966 table of the former Soviet Union was updated to 1972. Next, treating the top 10 percent largest 1972 coefficients as exogenous estimates, the remaining coefficients were updated via the same three methods. Comparison of the results indicates that exogenous determination of the largest coefficients does not change the methods' rankings while yielding substantial improvements in the forecasts. This paper was presented at the Forty-Sixth International Atlantic Economic Conference, Boston, MA, October 8–11, 1998.     

Portfolio flows and the US dollar–yen exchange rate

This paper investigates the effects of portfolio flows on the US dollar–Japanese yen exchange rate changes over the period 1988:01–2011:04. Using a time-varying transition probability Markov-switching framework, the results suggest that the impact of portfolio flows on the dollar–yen exchange rate changes is state-dependent. In particular, the results show that portfolio inflows from Japan toward the US, more than monetary variables, strengthen the probability of remaining in the dollar–yen appreciation (low volatility) state. Therefore, credit controls on the flows can be used as a policy tool to pursue economic and financial stability.     

Cross-sectional determinants of bank performance under deposit dollarization in emerging markets

Dollar-denominated deposits and loans could increase financial fragility in emerging market banking systems. This currency mismatch does not only increase banks' currency risk when the proportion of dollar-denominated loans with respect to local-denominated loans increases but also it increases their clients' default risk if depreciation occurs. This paper investigates the profitability of 36 dollarized banking systems. Results suggest that after controlling for some macroeconomic and institutional variables, dollarization, as the currency mismatch hypothesis suggests, depresses bank performance and lowers bank profitability. Results also show that the effect of institutions more than offsets the negative impact of dollarization on banks' profitability.     

Evaluating the Effect of Affinity Card Programs on Customer Profitability Using Propensity Score Matching

Affinity card programs have become popular in recent times and account for one fifth of all credit card accounts. There is no research that links affinity card programs to customer profitability. Moreover, little is known about what type of affinity card programs would lead to higher profit. Using a large proprietary dataset we answer the above questions. We also apply propensity score matching, a relatively new technique, to control for selection bias in addressing the above issues. Contrary to previous research and common belief, we show that affinity card customers are no more profitable than non-affinity card holders. We also show that sports-based affinity programs are the least profitable and surprisingly, alumni-based affinity programs also do poorly relative to other types of affinity. On the positive side, affinity card customers are lower risk and help to lower the average risk of the portfolio of customers.     

Wages, inflation, and mortgage design

By virtue of creating asset-liability mismatch, conventional long-term, fixed-rate mortgage loans inherently introduce excess interest risk to the financial systems. Considering that inflation is in part the reason for this excess interest risk, it seems natural to redesign mortgages in such a way that over time mortgage payments could, at least in part, reflect inflation. In this paper, I show that by allowing payments to adjust to inflation, particularly that of wages, by incorporating a prespecified growth rate into mortgage payments, mortgage loans become more affordable while bank interest spreads become less volatile, making the banking system less unstable.     

On uniform convergence of undiscounted optimal programs in the Mitra–Wan forestry model: The strictly concave case

In this paper, we show that the 1986 Mitra–Wan result establishing asymptotic convergence of maximal programs to the unique golden-rule forest in the case of undiscounted, strictly concave felicity functions can be strengthened, in the same setting, to the  uniform  asymptotic convergence of  optimal  programs to the unique golden-rule forest. We work with a notationally reformulated version of the model that may have independent interest.     

An examination of the relationship among consumer lifestyles,ethnocentrism, knowledge structures,attitudes and behavioural tendencies: a comparative study in two CIS states

The objective of this study is to investigate ethnocentric and/or regiocentric behaviour of Azeri and Kyrgyz consumers. In particular, the study focuses on how ethnocentrism explains consumers' attitudes, intentions and actual purchasing behaviour towards products from major sourcing countries. Data for the study were collected through personal interviews in four districts of Greater Bishkek: the capital city of Kyrgyz Republic, and Baku, the capital city of Azerbaijan. Survey findings lend greater support to earlier studies conducted in the USA, Western and Eastern Europe and Japan. Non-ethnocentric Kyrgyz and Azeri consumers have significantly more favourable belief structures, attitudes, intentions and the resultant purchasing behaviour regarding imported products compared to their ethnocentric Azeri and Kyrgyz consumer counterparts. The findings of the study offer important research, public policy and managerial implications for companies, government agencies and international donor agencies alike who are either operating in the region or contemplating an entry in the future. Foreign companies may use pan-regional marketing strategies and may be able to standardise their products and marketing strategies in the region, since consumers have identical and/or very similar use behaviour and uses for the products and services.     

House Prices and Inflation

The present paper examines the long-run impact of inflation on homeowner equity by investigating the relationship between house prices and the prices of nonhousing goods and services, rather than return series and inflation rates as in previous empirical studies on the inflation hedging ability of real estate. There are two reasons for this methodological departure from prior practice: (1) while the total return on housing cannot be accurately measured, the total return on housing is fully reflected in housing prices, and (2) given that using returns or differencing a time series leads to a loss of long-run information contained in the series, valuable long-run information can be captured by using prices. Also, unlike previous related studies, we exclude housing costs from goods and services prices to avoid potential bias in estimating how inflation affects housing prices. Monthly data series are collected for existing and for new house prices as well as the consumer price index excluding housing costs for the period 1968–2000. Based on both autoregressive distributed lag (ARDL) models and recursive regressions, the empirical results yield estimated Fisher coefficients that are consistently greater than one over the sample period. Thus, we infer that house prices are a stable inflation hedge in the long run.     

The Impact of Innovativeness and Development Time on New Product Performance for Small Firms

Timing is becoming a new source of competitive advantage. The business press extols the benefits of faster product development. This paper examines whether competitive advantage can be gained by reducing development time across all types of new products or whether this advantage is restricted to certain types of new products. It proposes that product innovativeness moderates the relationship between development time and initial market performance. A survey of 110 small manufacturing firms in computer related industries supports the hypothesis. The survey findings indicate that a firm must guard against over- or under-development of the new product since product innovativeness was found to influence the impact of development time on market performance. The implications for managers are: beware of bringing a new product that is too much, too early or too little, too late.
