Phineas Fletcher. Locustae vel Pietas Iesuitica
The bilingual English poet Phineas Fletcher (1582-1650) is the author of a short Latin epic on the Gunpowder Plot (1605). Mrs. Estelle Haan has provided the first critical edition based on all three manuscripts known and the original printed edition (Cambridge, 1627). After the introduction with an essay on the Gunpowder Plot literature in Latin (including poets, such as John Milton) follows the critical edition of Locustae vel Pietas Iesuitica with an English translation and an extensive commentary
Landscape 1:1, a study of designs for leisure in the Dutch countryside
Brinkhuijsen onderzoekt in haar dissertatie hoe recreatie in de loop van de twintigste eeuw een plek kreeg in het landschap en het landschapsontwerp, van de pioniersperiode (voor W.O. II), de massacrecreatie (jaren zestig), het recreatief medegebruik (rond 1980) to de huidige periode, die Brinkhuijsen kenmerkt met "verbreding". Ze analyseert ontwerpen die invloed hebben uitgeoefend op de manier waarop we recreatielandschappen nu zien, zoals het Amsterdamse Bos uit 1934, kleinschalige recreatielandschappen en een netwerk van fietspaden en wandelpaden in de landinrichting Oukoop-Kortrijk uit 1966, natuurontwikkelingsprojecten in het rivierengebied uit de jaren tachtig en negentig en de landschapsvisie voor de Drentsche Aa uit 2005. De achteraf wat schokkende conclusie luidt dat recreatie nauwelijks van belang is geweest in het landschapsontwer
Robust Covariance Matrix Estimation with Data-Dependent VAR Prewhitening Order
This paper analyzes the performance of heteroskedasticity-and-autocorrelation-consistent (HAC) covariance matrix estimators in which the residuals are prewhitened using a vector autoregressive (VAR) filter. We highlight the pitfalls of using an arbitrarily fixed lag order for the VAR filter, and we demonstrate the benefits of using a model selection criterion (either AIC or BIC) to determine its lag structure. Furthermore, once data-dependent VAR prewhitening has been utilized, we find negligible or even counter-productive effects of applying standard kernel-based methods to the prewhitened residuals; that is, the performance of the prewhitened kernel estimator is virtually indistinguishable from that of the VARHAC estimator.
Uses of National Accounts; History, International Standardization and Applications in the Netherlands
The national accounts is commonly known by its key-aggregates (e.g. GDP and saving) and their role in public debate and decision-making. However, the national accounts plays many different roles for many different uses. This paper provides an overview of the development of these roles and uses since the seventeenth century. Three periods are distinguished: the early estimates (1660-1930), revolutionary decades (1930-1950) and the era of the international guidelines (1950-present). The paper discusses these roles and uses also much more in detail for one country: the Netherlands, a country which played an important role in modern national accounting and where expert data users, like the CPB, SCP and the Dutch central bank, have developed several interesting applications of the national accounts.Uses of the national accounts, history of national accounting, history of taxation, economic growth, Dutch national accounts, relevance and reliability of the national accounts, Petty, King, Vauban, Quesnay, Keynes, Clark, Kuznets, Leontief, Tinbergen, Hicks, van Cleeff, Stone, Meade, guidelines on national accounting, European unification, macro-economic modeling and forecasting, CPB, SCP, Dutch central bank, fiscal policy, productivity analysis, performance management, national accounts and welfare, measurement in economics

New Keynesian Model Features that Can Reproduce Lead, Lag and Persistence Patterns
This paper uses a new method for describing dynamic comovement and persistence in economic time series which builds on the contemporaneous forecast error method developed in den Haan (2000). This data description method is then used to address issues in New Keynesian model performance in two ways. First, well known data patterns, such as output and inflation leads and lags and inflation persistence, are decomposed into forecast horizon components to give a more complete description of the data patterns. These results show that the well known lead and lag patterns between output and inflation arise mostly in the medium term forecasts horizons. Second, the data summary method is used to investigate a rich New Keynesian model with many modeling features to see which of these features can reproduce lead, lag and persistence patterns seen in the data. Many studies have suggested that a backward looking component in the Phillips curve is needed to match the data, but our simulations show this is not necessary. We show that a simple general equilibrium model with persistent IS curve shocks and persistent supply shocks can reproduce the lead, lag and persistence patterns seen in the data.output and inflation comovement, inflation persistence, forecast errors
The comovement between height and some economic development indicators in Spain
This paper investigates the relationship between height and some measures of human welfare in Spain for the period 1850-1978. For that purpose, we employ several filtering methods to measure the correlation between variables such as first order differences, deterministic trends, the Hodrick and Prescott filter, the band-pass filter or den Haan (2000)’s methodology which uses a new set of statistics to characterize the co-movement between variables to capture the dynamic between variables. We always find a strong and positive correlation between height and GDP per cápita, height and the weight of health services in total consumption, and height and openness. By contrast, we have a negative correlation between height and the mortality rate and height and the ratio between the deflator of private consumption and the GDP deflator. By applying den Haan (2000)’s method, we find that the comovement between height and GDP per cápita is always positive, increasing in the medium and long-run. This correlation is higher after the Spanish Civil War (1936-1939). We also observe that height and mortality rate have a negative correlation in the medium-run. Other health indicators such as the weight of health services in total consumption and the ratio between the deflator of private consumption and the GDP deflator show a positive and negative co-movement in the short-run, respectively. Nevertheless, they change their sign of correlation in the long-run. Finally, we observe a positive co-movement between height and illiteracy rate in the short-run, a negative one in the long-run, and a strong and positive comovement between height and the grade of openness.Height, physical stature, anthropometrics, education, economic development, VAR forecast errors

Decoupling and prices: determinant of dairy farmers’ choices? A model to analyse impacts of the 2003 CAP reform
The reform of European Common Agricultural Policy (CAP) in 2003 has resulted in substantial changes to the attribution of subsidies to dairy farmers. Moreover, dairy farmers are in also facing an unprecedented situation on the markets with the soaring prices of agricultural raw materials: they sell their products at a higher price (milk, meat and cereals), but must also cope with the increasing prices of concentrates. In this paper1, we discuss cross effects, on the productive strategy of French dairy farms, of the Luxemburg Agreement and the prices variations. A model based on mathematical programming has been privileged to determine how dairy farmers might re-evaluate their systems to identify optimal production plan. While respecting the principle of agent rationality (maximization of profit), the model incorporates the economic risk related to the volatility of the inputs and outputs prices. Thus the model maximises the expected utility of the income while taking into account a set of constraints: regulatory, structural, zootechnical, agronomic and environmental. The model is applied to four types of dairy farms to cope with the diversity of production systems in the west of France (“grazier” type, “semi intensive” type, “milk + cereals” type and “milk + young bulls” type). The model is used to produce quantitative estimations and support reflection through the simulation of the setting up of the Single payment scheme. The sensitivity of the results is discussed by taking into account several options of prices for cereals and livestock products. These may have a strong influence on the structure of the diet and, therefore, on the level of intensification of the forage area. The results show that the implementation of the CAP reform encourages farmers to substitute a part of corn silage by grass in the diet. However, the rising price of agricultural production encourages, on the contrary, farmers to intensify their system in order to free up land for growing cereals. We also observe that a decrease of the young bulls fattening activity to develop cereal crops is also economically profitable.dairy farm, single payment, price variation, Agricultural and Food Policy, Livestock Production/Industries,
