In this paper we show that Portugal benefitted from comparatively low-interest rates from the 13th century onwards, well before the generalised drop in interest rates in Europe. Contrary to the thesis that frontier economies struggle with high-interest rates and scarcity of capital, we find that the country's low and stable interest rates can be explained by its wide availability of land, combined with monetary stability and a favourable institutional network. These conclusions are built upon an entirely new dataset of interest rates and returns on capital for Portugal in the period 1230–1500.

Challenging current ideas in mainstream scholarship on differences between female labour force participation in southern and north-western Europe and their impact on economic development, this article shows that in Portugal, neither marriage nor widowhood prevented women from participating in the labour market of mid-eighteenth-century. Our research demonstrates that marriage provided women with the resources they needed to work in various capacities in all economic sectors.

This article also argues that single Portuguese women had an incentive to work and did so mostly as wage earners. Finally, the comparison of our dataset on female occupations from tax records with other European cases calls for a revision of the literature and the development of a more nuanced picture of the north-south divide.

In September 1939, Portugal made a realist strategic choice to preserve the Portuguese Empire maintaining by its neutrality and also remaining an ally of Great Britain. While the Portuguese could rely largely on their colonies for raw materials to sustain the mainland, the country had long depended on British transportation for these goods and the Portuguese military. With the British priority now given to war transportation, Portugal's economy and Empire were particularly vulnerable. The Portuguese dictator Antonio Salazar sought to mitigate this damage by maintaining particularly friendly financial relations with the British government, including increased exports of Portuguese merchandise and services and permission to accumulate credits in Sterling to cover deficits in the balance of payments. This paper gives an improved set of comprehensive statistics for the Anglo-Portuguese and German–Portuguese relationships, reported in Pounds and according to international standards. The reported statistics include the trade in merchandise, services, capital flows, loans and third-party transfers of funds in favour of the British account. When compared with the German statistics, the Anglo-Portuguese figures show the Portuguese government favoured the British in financial relations, an active choice by Salazar to maintain the Portuguese Empire.

In 1940, the Portuguese government approved a massive primary school construction plan that projected a 60 per cent increase in the number of primary schools. Based on the collection of a new dataset, we describe literacy levels in Portugal prior to the plan as well as the plan's strategy regarding the location of schools. We then estimate the causal impact of the increase in the number of schools between 1940 and the early 60s on enrolment and literacy, all at the county level. We conclude the increase in the number of schools was responsible for 80 per cent of the increase in enrolment and 13 per cent of the increase in the literacy rate of the affected cohorts.

We assess the numeracy (age heaping) of religious minorities, particularly Jews, and other defendants of the Spanish and Portuguese Inquisitions, and compare it with the general Iberian population. Our database includes 13,000 individuals who took part in Inquisition trials, and 17,000 individuals recorded in censuses and parish registers who serve as a control group. We thoroughly discuss the representativeness of our samples for the populations we aim to capture. Our results point at a substantial numeracy advantage of the Judaism-accused over the Catholic majority. Furthermore, Catholic priests and other groups of the religious elite who were occasional targets of the Inquisition had a similarly high level of numeracy.

What was the degree of Brazil's regional inequality in living standards during the first decades of the 20th century? This paper presents municipal and state information on wages and prices in order to build welfare ratios for skilled and unskilled workers between 1912 and 1940. Despite the significant differences in nominal wages and costs of living throughout the country, real wage differentials remained lower than those estimated by earlier studies. Williamson (1999) argued that real wages in the Southeast were approximately six times higher than in the Northeast during the 1930s. The new evidence in this paper suggests that wages were on average only 1.5 times higher.
