%description
An integrated and reproducible workflow for analysing the competitiveness
and risk of agricultural and horticultural exports. It measures
destination and product concentration (Herfindahl-Hirschman, entropy and
equivalent-number indices), revealed comparative advantage (Balassa, 1965)
<doi:10.1111/j.1467-9957.1965.tb00050.x> and its symmetric form, relative
unit values, and constant market share decomposition of export growth. It
tests vertical price transmission between export and domestic prices with
Engle-Granger cointegration (Engle and Granger, 1987)
<doi:10.2307/1913236> using MacKinnon (2010) critical values and symmetric
or asymmetric error correction models. It quantifies exchange-rate
exposure of a multi-currency export portfolio (volatility, diversification
ratio, risk contributions and value at risk), screens destination markets
with composite entry-risk scores, and identifies risk-efficient
destination mixes by mean-variance portfolio optimisation (Markowitz,
1952) <doi:10.2307/2975974>. Simulated example data for Indian mango,
grape, pomegranate and processed horticultural exports illustrate the
workflow.
