Inflation is a far from homogeneous phenomenon, a fact often neglected in modeling consumer price inflation.  Using a novel methodology grounded in theory, the ten sub-components of the consumer price index (excluding mortgage interest rates), are modeled separately and forecast,...

Inflation targeting central banks will be hampered without good models to assist them to be forward-looking.  Many current inflation models fail to forecast turning points adequately, because they miss key underlying long-run influences.  The world is on the cusp of a dramatic turning point in...

Empirical models of inflation often incorporate equilibrium correction effects based upon levels of prices and input costs. Such models assume that the steady-state price-cost markup is constant, but recent research suggests that this may not be true for the Euro area economy, which has...

Evolving openness to trade is hard to measure, despite its relevance to models of growth, inflation and exchange rates. Our innovative technique measures trade openness encompassing both observable trade policy (tariffs and surcharges) and unobservable trade policy (quotas and other non-tariff...

Despite the emerging consensus on the validity of purchasing power parity (PPP) between trading countries in the long run, empirical evidence in favour of the PPP theory is scarce in data predominantly exposed to real shocks. This paper tests for PPP between Norway and its trading partners using...

Inflation is a far from homogeneous phenomenon, but this fact is ignored in most work on consumer price inflation. Using a novel methodology grounded in theory, the ten sub-components of the consumer price index (excluding mortgage interest rates, or CPIX) for South Africa are modeled separately...

Despite the emerging consensus on the validity of purchasing power parity (PPP) between trading countries in the long run, empirical evidence in favour of the PPP theory is scarce in data predominantly exposed to real shocks. This paper tests for PPP between Norway and its trading partners using...

We build a 4-equation model of the inflation process in South Africa (which has recently adopted inflation targeting), including the exchange rate, consumer prices, producer price, and import prices. This provides useful information on the speed and extent of exchange rate pass-through, and...

Standard open economy models predict that openness to trade should exert a positive effect on the slope of the output-inflation tradeoff, or Phillips curve, but such a proposition finds very little support in the existing empirical literature. We propose a new test of this hypothesis based on...

A number of thoretical models predict that the slope of the Phillips curve increases with trade openness, but cross-country studies provide little evidence for such a correlation. We highlight two reasons for this finding. Firstly, the strength of the relationship may depend on the extent of...
