Since 1940 Mexico has increased exploration work in search of new oil fields. Most of the exploration has been done in the Gulf Coast area where all existing Mexican oil fields are located. A brief résumé is given of the main problems of the different provinces under exploration and a list of the fields discovered by Petróleos Mexicanos in the different provinces of the country. Geophysical methods have been responsible for location of a very large percent of the new fields. To compare the intensity of exploration in the United States and Mexico, the amount of seismic and gravity‐meter work and of wildcat drilling per million barrels of production is given for both countries. The data shows that Mexico’s level of geophysical exploration, per million barrels of oil produced, is very close to that of the United States. A very marked increase in the intensity of exploration is shown for both countries. Wildcat drilling in Mexico has been less intensive than in the United States but shows a definite tendency to increase; its present level is very close to that of the United States during 1940. The writer is of the opinion that the difference in intensity of wildcat drilling shown in the data presented is actually smaller than appears as there is a certain amount of duplication in the United States because of leaseholding problems.

Histories or reviews covering the period from 1922, the first year of petroleum geophysics in the United States, to 1940 were ably presented by Eckhardt, Macelwane and Weatherby at the Society of Exploration Geophysicists’ Annual Meeting of the latter year. This paper deals mainly with advances in geophysics since 1940. Marked progress has been made in the amount of geophysical activity, in the number of new oil fields discovered per year based wholly or partially on geophysics, in geophysical techniques, and in education. Improvements in instrumentation, field operational procedures, and interpretation methods have steadily increased the usefulness of the three major methods—seismic, gravity, and magnetic. The development of the aerial magnetometer, especially, and the underwater gravimeter represent notable achievements. These developments have made possible the extension of geophysical activity offshore, and in many other areas previously considered inaccessible. Advances have also been made in logging, particularly in the radioactivity type, geochemistry and electrical prospecting. Research, both fundamental and applied, is being conducted on a greater scale now than in 1940 or prior thereto. Increased geological‐geophysical coordination has led to better appreciation and utilization of the geophysical methods and has resulted in the discovery of important oil and gas reserves. Novel or more direct oil finding methods may possibly be discovered or perfected. It is more probable, however, that the future of exploration geophysics will be primarily in the continual refinement of the present known methods. Advances in exploration geophysics and geology, along with teamwork, should insure adequate production and reserves within the United States for a long period. This is predicated on our nation having competitive free enterprise, which has been responsible for the leadership of this country in oil finding, producing, transporting and refining techniques.

The year 1955 marks a continued decline in exploration for oil in the United States and in the world as judged from the employment of seismograph parties. The decline indicates that in the United States we have passed an upper limit of action within the framework of exploration practices as they have existed. The precipitate rise of geophysical exploration was due to the effort of exploration companies to be “firstest with the mostest.” The rapid coverage of prospective oil areas in the United States and in world, however, has not resulted in a complete exploration of the sedimentary areas. Many areas may be considered virtually unexplored. In addition, frontiers exist in the search for very‐small‐relief structures and stratigraphic traps by geophysical methods. Application of improved instruments, techniques, and interpretations to these problems will result in a new phase of sustained exploration with successes going to those with the most complete information and the best ideas. A changing geophysics will occupy an important place in the world petroleum economy, with at least 450 billion barrels of oil yet to be found.

The advent of exploration geophysics in the United States was in late 1922 when torsion balances were brought over to the United States from Germany by both the Roxana (the predecessor of Shell) and the Amerada Petroleum Corporation. The first survey in the Gulf Coast of Texas was at Spindletop in December, 1922, under the direction of Donald C. Barton, who later and at the time of his death in 1939 was Humble’s chief research geologist. It was Donald Barton’s idea that the known shallow piercement‐type salt dome at Spindletop would furnish a testing ground for this new method. It should be recorded that an excellent anomaly was found in this survey. Discouraging results followed, however, as other known structures were found to give no significant anomaly, and in other instances where anomalous areas were outlined they were condemned by the drilling of exploratory wells. In March, 1924—about a year and a half later—however, an outstanding anomaly was found in the Nash area, Fort Bend County, Texas. In November of that same year dome material was found by the drill, and the discovery of the Nash Dome was a reality. It was not until January 3, 1926, though, that oil was found on the flank of the dome, and this is probably the first oil found as a result of the use of geophysical methods in the United States.

In this paper, we use publicly available data from the Medical Expenditure Panel Survey - Insurance Component (MEPS-IC) to investigate the effect of Massachusetts' health reform plan on employer-sponsored insurance premiums. We tabulate premium growth for private-sector employers in Massachusetts and the United States as a whole for 2004 - 2008. We estimate the effect of the plan as the difference in premium growth between Massachusetts and the United States between 2006 and 2008—that is, before versus after the plan—over and above the difference in premium growth for 2004 to 2006. We find that health reform in Massachusetts increased single-coverage employer-sponsored insurance premiums by about 6 percent, or $262. Although our research design has important limitations, it does suggest that policy makers should be concerned about the consequences of health reform for the cost of private insurance.

The professional smuggling of mass consumption products develops when demand for a product is not adequately fulfilled by the legitimate market. The difficulties encountered in supplying are, in most contemporary cases, caused by real rarity of the desired product. For other cases, however, the rarity is largely virtual in that government taxes aimed at the product in question lead to increasing the product's price to a prohibitive end. This was the case with cigarettes in Canada between 1985 and 1994. Before both, the federal and provincial, governments decided to drastically decrease cigarette taxes in February 1994, the price for a pack of cigarettes was five to six times higher than the same product in the United States. This article begins with a brief review of the contribution made by economists in regard to contemporary smuggling. Focus will be aimed at common characteristics of the smuggling phenomenon across the world. Elements which are more particular to the Canadian smuggling situation will be identified as well. While the difference in the price of cigarettes between Canada and the United States would seem to be the undeniable driving force behind the development of smuggling activities at the countries ' border, one key question remains unexplained. Why was the volume of contraband unequally distributed across Canada even though the price of cigarettes remained largely consistent throughout all provinces? The level of organization of smuggling networks was much higher in Eastern Canada, and particularly in Quebec, than it was in the western provinces. It is argued that the reasons for this are not only due to price, but to a series of political, historical, and geographical factors which allowed cigarette smugglers to function better in Quebec than in the rest of the country.

The United States has never been culturally or religiously homogeneous, but its diversity has greatly increased over the last century. Although the U.S. was first a multicultural nation through conquest and enslavement, its present diversity is due equally to immigration. In this paper I try to explain the difference it makes for one area of thought and policy – equal opportunity – if we incorporate cultural and religious pluralism into our national self-image. Formulating and implementing a policy of equal opportunity is more difficult in diverse, pluralistic countries than it is in homogeneous ones. My focus is cultural and religious diversity in the United States, but my conclusions will apply to many other countries – including ones whose pluralism is found more in religion than in culture.

Unmarried cohabitation has become a more frequently observed phenomenon over the last three decades, and not only in the United States. The objective of this work is to examine income differentials between married women and those who remain single or cohabitate. The empirical literature shows that, while the marriage premium is verified in different studies for men, the result for women is not conclusive. The main innovation of my study is the existence of controls for selection. In this study, we have two sources of selectivity: into the labor force and into a marital status category. The switching regressions and the Oaxaca decomposition results demonstrate the existence of a significant penalty for marriage. Correcting for both types of selection, the difference in wages varies between 49% and 53%, when married women are compared with cohabiting ones, and favors non-married women. This result points to the existence of a marriage penalty.
