The Bishop-Simpson model, a variant _of the traditional shift-share approach, is utilized for investigation of the development of the southern New Hampshire regional economy over time. Emphasis is placed on the strengths of the new technique in counteracting some of the limitations of traditional shift-share analyses. The B and S technique gives a clearer picture than the traditional shift-share approach of the relative advantages an disadvantages for region in terms of its specialization m slow or fast growing industries.
Bishop-Simpson模型是传统偏移-份额方法的一种变体,用于调查新罕布什尔州南部地区经济随时间的发展。重点放在新技术的优势,以抵消传统的转移份额分析的一些局限性。与传统的转移-份额方法相比,B和S技术更清晰地反映了地区在慢速或快速增长产业专业化方面的相对优势和劣势。

Pub Date : 1978-04-01 DOI: 10.1017/S0163548400001990
J. P. Kuehn, E. Hamer
The objective of the paper was to bring together some of the preexisting theoretical treatments ~f dummy variables in regression analysis and to present them in such a way as they could be more effectively used and interpreted. This Will enable researchers to select the particular representation that best suits their hypotheses. Four alternatives were exhibited for both a one-way analysis of variance and a one-way analysis of variance with a covariate. The predicting equations were presented in the text of the paper along with numerical examples and their interpretations. The derivations of the predicting equations and variable definitions were presented in the Appendix.
本文的目的是汇集一些先前存在的理论处理~在回归分析中的虚拟变量,并提出这样一种方式,使他们可以更有效地使用和解释。这将使研究人员能够选择最适合他们假设的特定表示。对于单向方差分析和带有协变量的单向方差分析,展示了四种备选方案。文中给出了预测方程,并给出了数值算例及其解释。预测方程的推导和变量定义在附录中给出。

A Mail/Telephone Technique For Collecting Primary Data 收集原始数据的邮件/电话技术
Pub Date : 1978-04-01 DOI: 10.1017/S0163548400001977
R. W. Smith, J. Conrad, D. A. Storey
A mail/telephone technique is discussed which achieved a 79 percent response rate at a cost per usable survey which was only about 50 percent above the general average costs for using mailed questionnaires. With proper follow-up techniques this method is capable of yielding even higher response rates at a cost far below personal, face-to-face interviews.

Multicollinearity; effects, symptoms, and remedies. 多重共线性;效果、症状和补救措施。
Pub Date : 1978-04-01 DOI: 10.1017/S0163548400001989
C. Willis, R. Perlack
Multicollinearity is one of several problems confronting researchers using regression analysis. This paper examines the regression model when the assumption of independence among Ute independent variables is violated. The basic properties of the least squares approach are examined, the concept of multicollinearity and its consequences on the least squares estimators are explained. The detection of multicollinearity and alternatives for handling the problem are then discussed. The alternative approaches evaluated are variable deletion, restrictions on the parameters, ridge regression and Bayesian estimation.
多重共线性是回归分析研究人员面临的几个问题之一。本文研究了在不满足自变量独立假设的情况下的回归模型。研究了最小二乘方法的基本性质,解释了多重共线性的概念及其对最小二乘估计量的影响。然后讨论了多重共线性的检测和处理问题的替代方法。评估的备选方法有变量删除、参数限制、脊回归和贝叶斯估计。

WATER-RAIL RATE COMPETITION AND THE COMPETITIVE POSITION OF THE NORTHEASTERN POULTRY INDUSTRY 水铁费率竞争与东北家禽业的竞争地位
Pub Date : 1978-04-01 DOI: 10.1017/S0163548400001916
W. Spilka, D. Kenyon, L. Shabman
Differential grain transportation rates between the Northeast and South have been identified as a possible source of comparative disadvantage for Northeastern broiler producers. Low cost barge transportation into the South provides competition for railroads resulting in generally low transportation rates in the South. Barge transportation is low cost in part because the Federal improvements of waterways have resulted in a toll-free waterway system. Solutions for a transportation model were found with and without the subsidy. The results indicate that subsidy removal is unlikely to affect interregional broiler production and consumption.
东北和南方之间的粮食运输率差异已被确定为东北肉鸡生产商相对劣势的可能来源。进入南方的低成本驳船运输为铁路提供了竞争,导致南方的运输费率普遍较低。驳船运输成本低的部分原因是联邦政府对水路的改善已经形成了一个免收费的水路系统。找到了有和没有补贴的交通模式的解决方案。结果表明,取消补贴不太可能影响区域间肉鸡生产和消费。

FISCAL IMPACTS OF CHANGES IN POPULATION FOR NON METROPOLITAN AREAS OF THE NORTHEAST 人口变化对东北非大都市地区的财政影响
Pub Date : 1978-04-01 DOI: 10.1017/S0163548400001953
W. Fox, P. Sullivan
The recent reversal in the intraregional migration into nonmetropolitan areas has generated a great deal of interest in the problems of local government finance .. or specific concern are the changes in local government expenditures and revenues that have accompanied population growth and decline and related shifts in population composition in nonmetropolitan areas of the Northeast. Using a supply and demand framework, it is argued that the approach used in previous studies of examining the relationship between growth rates and various fiscal variables leads to biased inferences regarding the impact of growth. By analyzing the impacts of changes in the socioeconomic make-up of the population which often accompany growth and decline, the study increases the understanding of fiscal strains on local governments resulting from population shifts.
最近,区域内人口向非大都市地区迁移的趋势发生逆转,这引起了人们对地方政府财政问题的极大兴趣。特别值得关注的是,东北非大都市地区的地方政府支出和收入的变化伴随着人口的增长和下降以及相关的人口构成变化。使用供给和需求框架,本文认为,以前研究增长率与各种财政变量之间关系的方法导致了关于增长影响的有偏见的推断。通过分析人口社会经济构成变化的影响,这种变化通常伴随着增长和下降,该研究增加了对人口变化导致的地方政府财政压力的理解。

Causes Of Low Returns To Farm Labor In The U.S.: An Analysis Of Factor Market Interactions 美国农业劳动报酬低的原因:一个要素市场相互作用的分析
Pub Date : 1978-04-01 DOI: 10.1017/S0163548400001904

Despite massive off-farm migration and relatively prosperous agricultural years, estimates of returns to factors of production indicate that labor earnings in agriculture remain low. This is primarily caused by farm factor market characteristics and the resulting tendency of any increase in farm income to be capitalized into land values.
尽管有大量的非农移民和相对繁荣的农业年份,对生产要素回报的估计表明,农业劳动收入仍然很低。这主要是由于农业要素市场的特点以及由此产生的农业收入的任何增加都被资本化为土地价值的趋势造成的。

A SPATIAL ANALYSIS OF WESTERN NEW YORK CORN PRICES 纽约西部玉米价格的空间分析
Pub Date : 1978-04-01 DOI: 10.1017/S0163548400001928
S. K. Riggins
This paper develops the methodology used to investigate the pricing efficiency of farm level corn prices in a minor surplus production area (Western New York) located Within a much larger regionally deficit, producing area. The results Indicate that from January 1975-June 1976, farm level corn prices in Western New York were not competitively efficient. However, Western New York corn prices were competitively efficient after mid June 1976. A conclusion is that Western New York corn prices became competitively efficient after two new relatively large buyers located in the area.
本文开发了一种方法,用于调查位于更大的区域赤字生产区的少量剩余生产区(纽约西部)农场级玉米价格的定价效率。结果表明,1975年1月至1976年6月,纽约州西部农场水平的玉米价格不具有竞争效率。然而,1976年6月中旬之后,纽约西部的玉米价格具有竞争力。结论是,在两个相对较大的新买家进入该地区后,纽约西部的玉米价格变得具有竞争力。
